Motion Acceleration is the rate at which the velocity of a moving object changes. That is, acceleration is the derivative of velocity. If time is measured in seconds and velocity in feet per second, then acceleration is measured in feet per second squared, or ft/s2.
Suppose a car is moving with velocity
a. Find the car's velocity at t = 12.
b. Find the car's acceleration at t = 12.
c. Interpret your answer to part b in words.
d. Suppose s(t) is the car's distance, in feet, from its starting point. Find an equation for s(t).
e. Find the distance the car travels in the first 12 seconds.
