7. What is the rate of change of a car's velocity if the car goes from 35 mph to 41 mph in its
first second, then 41 mph to 47 mph in the next second, and then 47 mph to 53 mph in
the third second?
8. What is the rate of acceleration of a car that goes from v = 14 m/s to v = 4 m/s in 0.5
seconds?
9.
How much time will it take a car initially traveling at 4 m/s and accelerating at 6.5 m/s² to
reach a velocity of 95 m/s?
