Look at the velocity versus time graph below. What is the magnitude of the displacement of the object after it travels for three
Elza [17]

Answer:

C. 12m

Explanation:

veocity =  \frac{displacement}{time}

from the graph v = 4m/s and t = 3 s

d = vt = 4 × 3 = 12 m

inn [45]
Force=tension-fg sin ∅
=140-mg sin 18.5
=140-124.35
=15.62N

a=f/m=15.62/40=0.39
now,
v²=u²+2as
=2×0.39×80
v²=62.4
v=7.8m/s

frez [133]

Answer:

<h2>Stunt car A and stunt car B are identical cars with the same mass of 35.9 kg. They are both traveling at 37.1 m/s. Stunt car A crashes into a hard concrete wall, whereas stunt car B crashes into a big soft mattress. They both come to a complete stop after the impact.Stunt Car A experiences a <u>LARGE FORCE</u> over a <u>SHORT PERIOD</u> of time. Stunt Car B experiences a <u>SMALL FORCE</u> over a <u>LONG PERIOD</u> of time. Because of the force experienced by Stunt Car A, it will sustain <u>MORE</u> damage than Stunt Car B.</h2>

Explanation:

As we know that force is given as rate of change in momentum

so it is defined as

F = \frac{dP}{dt}

so here we know that both the cars are identical and both are moving with same speed so after coming to rest both the cars have same change in momentum

while Car A will experience more force because due to collision with concrete wall the time of collision is very small as compared to Car B

So Force on Car A is more than the force on Car B
