The position function for the car is , where s is measured in feet and t is measured in seconds. What is the velocity function for the car? What is the acceleration function for the car? How long does it take the car to stop? Answer this question Show less Calculus

Explanation / Answer

1. v = v(initial) + acceleration * time

v(initial) = 0 because the object was at rest, therefore it's just accel. * time

2. a = change in velocity / change in time

That is: (ending velocity (found from 1.) - initial velocity (which is 0 again) ) / (ending time - initial time (which is 0))

3. t = (v(final) - v(initial)) / a

These variables are found from 1. and 2.
