You flip a coin straight up if the coin reaches a high point of 0.25 m above where you released it what was the initial speed?
Answer: 2.21 m/s
Explanation:
Given
Coin reaches a height of 0.25 m above the launch point
Suppose u is the initial speed of the coin
Using the equation of motion
[tex]\Rightarrow v^2-u^2=2as\\[/tex]
Putting values
[tex]\Rightarrow 0^2-u^2=2\times g\times s=2\times (-9.8)\times 0.25\\\Rightarrow u^2=4.9\\\Rightarrow u=2.21\ m/s[/tex]
Thus, the initial velocity is 2.21 m/s
Does gravity affect kenetic energy
Answer:
Yep.
Explanation:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. Gravity will pull the object down. So yes, gravity affects kinetic energy.
Answer:
Kinetic energy is energy an object has because of its motion. A ball held in the air, for example, has gravitational potential energy. If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.

The passenger has a stopwatch.
The lamp posts are 40 m apart.
lamp post
Figure 4
Describe how the passenger could determine the speed of the car as accurately
as possible.
(3)
Answer:
To calculate anything - speed, acceleration, all that - we need data. The more data we have, and the more accurate that data is, the more accurate our calculations will be. To collect that data, we need to measure it somehow. To measure anything, we need tools and a method. Speed is a measure of distance over time, so we'll need tools for measuring time and distance, and a method for measuring each.
Conveniently, the lamp posts in this problem are equally spaced, and we can treat that spacing as our measuring stick. To measure speed, we'll need to bring time in somehow too, and that's where the stopwatch comes in. A good method might go like this:
Press start on the stopwatch right as you pass a lamp postEach time you pass another lamp post, press the lap button on the stopwatchPress stop after however many lamp posts you'd like, making sure to hit stop right as you pass the last lamp postRecord your dataCalculate the time intervals for passing each lamp post using the lap dataCalculate the average of all those invervals and divide by 40 m - this will give you an approximate average speedOf course, you'll never find an *exact* amount, but the more data points you have, the better your approximation will become.

how much kinetic energy is produced when an object having mass of 50gm throwing with velocity 80m/s?
Answer:
KE = 160 J
Explanation:
KE = 1/2mv²
mass= 50gm = 0.05kg
velocity = 80
KE = 1/2 x 0.05 x 80²
= 1/2 x 0.05 x 6400
= 160
The kinetic energy produced in an object is equal to 160 J.
What is the kinetic energy and potential energy?The energy possessed by a moving body due to its motion is known as kinetic energy. Work must be done in order to change the kinetic energy of a moving object.
The kinetic energy of a moving body can be measured from the formula mentioned below:
K.E. = ½mv² where ‘m’ is the mass and ‘v’ is the velocity of the object.
Potential Energy (P.E.) can be described as the stored energy in an object due to its position and is expressed as P.E = mgh where m, g, and h are the mass, gravitational acceleration, and height respectively.
Given, the mass of the object =, m = 50 g = 0.05 Kg
The velocity of the object, v = 80 m/s
The kinetic energy = (1/2)× 0.05 ×(80)²
K.E. = 160 J

a bomb is dropped from a plane fying at a constant horizontal velocity at an altitude of 300m. where is the bomb after 2 seconds?
Answer:
it will be almost on the ground
Explanation:
i say this because the boom is heavy and its going down fast so it will not be in the air or on the floor it will be akmost o the ground.

Water uptake to the atmosphere occurs through the processes of evaporation and transpiration from plants where it condenses to form clouds. Clouds release the water through precipitation. During a summer of extreme drought, what can we expect to happen to the surface groundwater stored in ponds and lakes?
a. Water levels will increase because there is more precipitation
b. Animals won't drink as much to save water, so water levels remain the same
c. Water levels will increase because there are more evaporation and transpiration
d. Water levels will decrease because there are more evaporation and transpiration
water level will decrease because there are more evaporation and transpiration

What is the acceleration of a bike that starts from rest and after 10s is traveling 20m/s?
Answer:
10meter per second square
Explanation:
since the bike is from rest, the initial velocity is zero and the final velocity is 20m/s . so by formula a=v-u/t
a = 20-0/10
a = 2
How much kinetic energy does 150kg boulder have if it is rolling down a hill with a speed of 5m/s? (KE = 1/2mv2) 375J 310J 1875J 1500J
Answer:
1875J
Explanation:
KE = 1/2mv2
=0.5 × 150kg × 5m/s^2
= 1875J
Therefore, the kinetic energy of the boulder is 1875J.
If the wheel then slows to rest in 9.46 s while making a quarter turn, calculate the magnitude of its average angular speed during that time.
Answer:
0.16 rad /s
Explanation:
Given that :
Time, t = 9.46 s
Quarter turn = 1/4 rev
θ = wt
w = angular speed `. ; t = time in second
1 rev = 2 pi
θ = 2pi
1/4 θ = 1/4 * 2pi = pi/2
θ = wt
pi/2 = w * 9.62
3.14 = w * 9.62 * 2
3.14 = 19.24w
w = 3.14 / 19.24
w = 0.1602040
w = 0.16 rad /s
What is the velocity of an 80 kg person skating across the ice with a kinetic energy of 16, 000 joules?
Answer:
V = 20 m/s
Explanation:
Given the following data;
Mass = 80kg
Kinetic energy = 16,000 joules
To find the velocity;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the formula, we have;
16000 = ½*80*V²
16000 = 40V²
V² = 16000/40
V² = 400
Taking the square root of both sides, we have;
V = 20 m/s
