What is the rate of acceleration of a mountain bike if it slows down from 9.4 m/s to 3.0 m/s in a time of 3.75 s?

a = vf – vi / t

A policeman traveling 19.5 m/s spots a speeder ahead, so he accelerates his vehicle at a steady rate of 1.81 m/s² for 3.2 s, at which time he catches up with the speeder. What distance does the police car cover in that time?

d = v_it + ½ at²

A car parked on a hill starts to coast down the hill, accelerating from rest at a constant rate of 0.45 m/s². How fast will the car be moving after 7.0 s?

v_f = v_i + at

An airplane accelerates down a runway from rest at 3.98 m/s² for 25.9 s until it lifts off the ground. Determine the distance traveled before takeoff.

d = v_it + ½ at²

A ball is dropped from a building. How fast is it traveling after falling for 1.77 s?

v_f = v_i + at
