A Prius moving at a speed of 20 m/s begins to slow down at a constant rate of 3.0 m/s each second. Find how far it goes before stopping. (Remember that when the Prius stops, its final velocity =0)
Homework Answers
Using the equation of motion :
v^2= u^2 + 2as
v = 0
u = 20 m/s
a = -3 m/s2
So, 0^2 = 20^2 + 2*(-3)*s
So, s = 66.7 m <-------- answer

The brakes are applied to a moving car, causing it to uniformly slow down. While slowing, it moves a distance of 40.0 m in 7.65 s to a final velocity of 1.95 m/s, at which point the brakes are released (a) What was its initial speed (in m/s), just before the brakes were applied?(b) What was its acceleration (in m / s²) while the brakes were applied? (Assume the initial direction of motion is the positive direction. Indicate the direction with the...

A 2000 kg truck is moving with speed 20 m/s. A 1000 kg car is moving with speed 40 m/s. Both apply the brakes, which exert the same constant braking force, and are brought to rest. Which vehicle travels the greatest distance before stopping? I'm looking for a worked out example, thanks!
