Answer:
The truck because it has more weight to slow it down also it's only going 10mph
The Ferrari with less momentum will stop first.
The given parameters:
Mass of the freight, m1 = 5000 ton = 4535924 kgSpeed of the freight, v1 = 10 mph = 4.47 m/sMass of the Ferrari, m2 = 3250 lb = 1474.175 kgSpeed of the Ferrari, v2 = 250 mph = 111.76 m/sThe momentum of each vehicle is calculated as follows;
P1 = m1v1 = 4535924 x 4.47 = 20,275,580.28 kgm/s
P2 = m2v2 = 1474.175 x 111.76 = 164,753.8 kgm/s
[tex]Ft = mv\\\\t = \frac{mv}{F}[/tex]
When the same force is applied, the object will less momentum will stop first.
Since the vehicle less momentum will stop first, thus we can conclude that the Ferrari with less momentum will stop first.

Hey can someone please help answer this question?
A child rides near the edge of a merry-go-round that rotates on a frictionless axis. If the child walks
toward the center of the merry-go-round, will the angular momentum change if a) the child is the
system? b) the system is the child-merry-go-round
Wouldn’t the two be the same? Because it is simply speaking about the child’s angular momentum?

A ball with an initial velocity of 12 m/s is rolling up a hill. The ball accelerates at a rate of -2.6 m/s/s.
Answer:
4.61 seconds
Explanation:
Given data
Initial velocity= 12m/s
acceleration= -2.6m/s^2
From the given data
we can find the time t
we know that
Acceleration= velocity/time
time= velocity/acceleration
time= 12/2.6
time= 4.61 seconds
MC Qu. 82 A design engineer wants to construct a sample... A design engineer wants to construct a sample mean chart for controlling the service life of a halogen headlamp his company produces. He knows from numerous previous samples that this service life is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. On three recent production batches, he tested service life on random samples of four headlamps, with these results: Sample Service Life (hours) 1 495 500 505 500 2 525 515 505 515 3 470 480 460 470If he uses upper and lower control limits of 520 and 480 hours, what is his risk (alpha) of concluding servicelife is out of control when it is actually under control (Type I error)? A. 0.0026B. 0.0456C. 0.3174D. 0.6826E. 0.9544
Answer:
B) 0.0456
Explanation:
It is given that :
Rationale :
UCL = 480
LCL = 480
∴ Mean , [tex]$\bar X = 500$[/tex]
The standard deviation of sample (Sn) = 11.55
Z (for UCL) [tex]$=\frac{\text{UCL - Mean}}{\text{Sn}}$[/tex]
[tex]$=\frac{520-500}{10}$[/tex]
= 2
Similarly,
Z (for LCL) [tex]$=\frac{\text{LCL - Mean}}{\text{Sn}}$[/tex]
[tex]$=\frac{480-500}{10}$[/tex]
= -2
Now using the z table for finding the confidence level between Z value of -2 and 2.
Confidence level = 0.4772 + 0.4772
= 0.9544
Risk (alpha) = 1 - confidence level
= 1 - 0.9544
= 0.0456

in a nuclear plant, 1 * 10 ^27 J of energy is available from mass conversion How much mass was lost ?
Answer:
[tex]1.2\times 10^{10}\ kg[/tex]
Explanation:
Given that,
The energy of the nuclear plant, [tex]E=10^{27}\ J[/tex]
We need to find how much mass wast lost.
The relation between energy and mass is given by :
[tex]E=mc^2[/tex]
Where
c is speed of light
[tex]m=\dfrac{E}{c^2}\\\\m=\dfrac{10^{27}}{(3\times 10^8)^2}\\\\m=1.2\times 10^{10}\ kg[/tex]
So, [tex]1.2\times 10^{10}\ kg[/tex] of mass was lost.

Why does a lunar eclipse last for a few hours whereas a solar eclipse only lasts for a few minutes?
Select one:
a.
The moon takes more time to travel through the earth’s umbra.
b.
Because the moon is moving much more slowly than the sun.
c.
Solar and lunar eclipses actually last about the same time.
d.
Because the sun is stationary and the moon is moving.
Answer:
The type and length of a lunar eclipse depend on the Moon's proximity to either node of its orbit. ... A total lunar eclipse can last up to nearly 2 hours, while a total solar eclipse lasts only up to a few minutes at any given place, due to the smaller size of the Moon's shadow.
1/2 means that the voltage (or charge) of the system will increase to half more of what is left in a time equal to t1/2 seconds. Therefore if a system is already at half charge (t1/2 seconds after starting) then after t1/2 more seconds the system will be charged to 50% plus half of 50%. That is 25% more, or 75% of the entire charge. Let's say that four t1/2's have gone by. That means that the charge (or voltage) is at (50% + 1/2*50% + 1/2*1/2*50% + 1/2*1/2*1/2*50%) = 93.75% of maximum charge. Yikes! Now look in your manual for a more simple mathematical derivation of this concept. Given t1/2 to be 0.4406 seconds, how long should it take to reach 75% of maximum charge? answer in seconds.
Answer:
The answer is "0.047".
Explanation:
Given value:
[tex]\to t_{\frac{1}{2}}= 0.4406\\\\\to V=0.9375 V_{max}[/tex]
Calculating the capacitance:
[tex]\to V=V_{max} (1-e^{\frac{-t}{Rc}})[/tex]
In this, the t = time, which is taken to calculates its maximum voltage.
[tex]\to 0.9375 V_{max} = V_{max}(1-e^{- \frac{t}{103\times(165.279\times10^{-6})}})\\\\\to e^{- \frac{t}{103\times(165.279\times10^{-6})}}= 0.0625\\\\\to - \frac{t}{103\times(165.279\times10^{-6})} = \ln(0.0625)\\\\\to -t= 0.01702\times(-2.77258) \\\\ \to -t = -0.04719 \\\\ \to t= 0.04719 \approx 0.047 \ s[/tex]

-A 180 kg hippo is riding a bicycle at a speed of 6.0
m/s. Out of nowhere, a chimpanzee runs out in the
hippo's path and he must slam on his brakes. If the
bicycle's brakes exert a force of 1600 N, how
long will it take to stop the bicycle? _s
Answer:
0.0675 seconds
Explanation:
From the question,
We apply newton's second law of motion
F = m(v-u)/t.................... Equation 1
Where F = force exert by the brake, v = final speed, u = initial speed m = mass of the bicycle, t = time.
make t the subject of the equation
t = m(v-u)/F................... Equation 2
Given: m = 180 kg, u = 6.0 m/s, v = 0 m/s (comes to stop), F = -1600 N ( agianst the dirction of motion)
Substitute these value into equation 2
t = 180(0-6.0)/-1600
t = -1080/-1600
t = 0.0675 seconds.

What is the kinetic energy of a 0.500 kg toy car moving at a state of 1.50 m/s
Answer:0.563
Explanation:
The kinetic energy produced in a toy car is equal to 0.563 J.
What is the kinetic energy and potential energy?The energy exhibited by a moving body because of its motion is said to be its kinetic energy. Work should be done which can change the kinetic energy of a moving object.
The kinetic energy of a moving object can be determined from the formula mentioned below:
K.E. = ½mv² where ‘m’ and ‘v’ is the mass, velocity of the object.
Potential Energy (P.E.)is energy that is stored in an object due to its position and can be expressed as P.E = mgh where h, m, and g are the height, mass, and gravitational acceleration respectively.
Given, the mass of the toy car =, m = 0.500 Kg
The velocity of the toy car, v = 80 m/s
The kinetic energy = (1/2)× 0.500 ×(1.50)²
K.E. = 0.563 J
