At an amusement park, a swimmer uses a water slide to enter the main pool If the swimmer start at rest slides without friction and descend through a vertical height of 2.31m what is her speed at the bottom of the slide

Answers

Answer:

v = 6.72 m/s

Explanation:

Given that,

Vertical height, h = 2.31 m

We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,

[tex]\dfrac{1}{2}mv^2=mgh\\\\v=\sqrt{2gh}[/tex]

Put all the values,

[tex]v=\sqrt{2\times 9.8\times 2.31} \\\\v=6.72\ m/s[/tex]

So, her speed at the bottom of the slide is equal to 6.72 m/s.

Based on Newton's law of motion, which combination of rocket bodies and engine will result in the acceleration of 40 m/s ^2 at the start of the launch?

Answers

The question is incomplete. The complete question is :

The Rocket Club is planning to launch a pair of model rockets. To build the rocket, the club needs a rocket body paired with an engine. The table lists the mass of three possible rocket bodies and the force generated by three possible engines.

A 4-column table with 3 rows. The first column labeled Body has entries 1, 2, 3. The second column labeled Mass (grams) has entries 500, 1500, 750. The third column labeled Engine has entries 1, 2, 3. The fourth column labeled Force (Newtons) has entries 25, 20, 30.

Based on Newton’s laws of motion, which combination of rocket bodies and engines will result in the acceleration of 40 m/s2 at the start of the launch?

Body 3 + Engine 1

Body 2 + Engine 2

Body 1 + Engine 2

Body 1 + Engine 1

Solution :

Given :

Body       Mass (gram)     Engine      Force (newtons)

1                   500                 1                     25

2                  1500                2                    20

3                  750                  3                    30

The body 1 has a mass of 500 gram which is equal to 0.5 kg

And engine 2 has a force of 20 newtons.

We know that according to Newton's laws of motion,

Force = mass x acceleration

 20    = 0.5 x acceleration

Acceleration [tex]$=\frac{20}{0.5}$[/tex]

                      [tex]$=\frac{200}{5}$[/tex]

                      [tex]$= 40 \ m/s^2$[/tex]

Therefore, based on laws of motion of Newton, the Body 1 + Engine 2 combination of the rocket bodies and engines will result in an acceleration of [tex]$ 40 \ m/s^2$[/tex] at the start of the launch.

Assume you have a person with a mass of 65 kg riding a skateboard down a ramp. While they are
still 4.8 m high, they are traveling at a speed of 8.0 m/s.
a) Calculate the Eg. [write here)
b) Calculate theEk [write here]
c) Calculate the Etotal. [write here]
d) If the ramp had a total height of 8.0 m, what would be their Eg, Ek, and Etotal at that height?

Answers

Answer:

a) Eg = 3,060.72 j

b) Ek = 2,080 j

c) Etotal = 5,140.72 j

d) Eg = 5,140.2 j

Ek = 0 j

Etotal = 5,140.2 j

Explanation:

The given parameters of the person riding the skateboard are;

The mass of the person, m = 65 kg

The height of the person (above ground level), h = 4.8 m

The speed at which the person is traveling, v = 8.0 m/s

a) The gravitational potential energy, Eg = m·g·h

Where;

m = The mass of the object at the given height = 65 kg

g = The acceleration due to gravity, g ≈ 9.81 m/s²

h = The height by which the object is elevated = 4.8 m

∴ Eg = 65 kg × 9.81 m/s² × 4.8 m = 3,060.72 joules

The gravitational potential energy, Eg = 3,060.72 J

b) The kinetic energy, Ek, is given as follows;

Ek = 1/2·m·v²

Where;

v = The velocity of the object = 8.0 m/s

∴ Ek = 1/2 × 65 kg × (8.0 m/s)² = 2,080 joules

The kinetic energy, Ek = 2,080 J

c) The total mechanical energy, Etotal = Eg + Ek

∴  Etotal = 3,060.72 j + 2,080 j = 5,140.72 J

The kinetic energy, Ek = 5,140.72 J

d) If the ramp had a total height of 8.0 m, we have;

At the 8.0 m height

Etotal = Eg(max), Ek = 0 j

With the given values, we get;

Eg(max) = 65 kg × 9.81 m/s² × 8 m = 5,101.2 joules = Etotal

Eg(max) = 5,101.2 j

Etotal = 5,101.2 j

Ek = 0 j

However, using only the values in the question with the assumption that all things being equal, we have;

Etotal = Constant = 5,140.72 j

Eg a the max height, 8.0 m = Eg(max) = Etotal = 5,140.2 j

Ek = 0 j

What is Momentum ?

Momentum is a concept in physics that describes an object's tendency to continue moving in its current direction at a constant speed. It is a vector quantity, meaning it has both magnitude and direction. The momentum of an object is defined as the product of its mass and velocity, and is represented by the equation: p = mv, where p is momentum, m is mass, and v is velocity.

In simple terms, momentum can be thought of as the "motion" of an object, and the larger the mass and velocity of an object, the greater its momentum. Momentum is a conserved quantity, which means that the total momentum of a system remains constant unless acted upon by an external force.

Given , Mass = 1000kg

Speed = 20 m/s

momentum = mv = 20000 kg m /s

David put a plant in a black box as shown. The box also had a black lid to cover the front. David only opened the box to add water to the plant. The plant stayed in the box for 10 days. When David took the plant out of the box on the tenth day, the plant was dead. Why did the plant dead only after ten days in the box?

Answers

Answer:

the plant died because of lack of sunlight

Explanation:

A plant gets its food from the photosynthesis process, which combines CO₂ and H₂0 into carbohydrates, the two substances are in the box, but for this they need energy from sunlight.

           CO₂ + H₂O + Sunlight /chlorophyll → (CH₂0)ₙ + O₂

the extra oxygen is released into the atmosphere.

Therefore the plant died because of lack of sunlight

3. A warehouse employee is pushing a 30.0 kg desk across a floor at a
constant speed of 0.50 m/s. How much work must the employee do on
the desk to change the speed to 1.00 m/s?

Answers

Answer: The employee must do 11.2308 Joules of work

Explanation:

Work done = force × distance

But  

Force = ma(mass x acceleration due to gravity)

F = 30×9.8

F = 294N

Also distance moved can be found using  the equation  

v² = u² +2gS

1.00 ² = 0.50²+2(9.8)S

1 =0.25+19.6S

1-0.25 =19.6S

0.75=19.6S

S=0.75/19.6

S = 0.0382m

Work done = force × distance = FS

Work done = 294 N X 0.0382m

Workdone =11.2308Nm = 11.2308 Joules

Work done required by the employee to do on the desk to change the speed to 1.00 m/s is 11.3 J.

What is work done?

Work done is the force applied on a body to move it over a distance. Work done by a body can be given as,

[tex]W=Fd[/tex]

Here (F) is the magnitude of force and (d) is the distance traveled.

From the second law of motion, the force is product of mass time acceleration. Thus the above formula can be given as,

[tex]W=(ma)d[/tex]

For the gravitational acceleration, it can be written as,

[tex]W=(mg)d\\W=mgd[/tex]

The constant speed by which, the warehouse employee is pushing the desk across a floor is 0.50 m/s and the the final speed of the desk is 1 m/s.

Thus, the distance traveled by it can be find out using the third law of motion as,

[tex]v^2-u^2=2gd\\1^2-0.25^2=2\times9.8\times d\\d=0.0382\rm m[/tex]

As the mass of the desk is 30 kg and the distance moved is 0.382 meters. Thus, put the values in the above formula as,

[tex]W=30\times9.81\times0.0382\\W\cong11.3\rm J[/tex]

Thus the work done required by the employee to do on the desk to change the speed to 1.00 m/s is 11.3 J.
