a car is traveling at a steady 72 km/h in a 50km/h zone. a police motorcycle takes off at the instant the car passes it, accelerating at a steady 8.1m/s^2. How much time elapses before the motorcycle is moving as fast as the car?

Police moves with acceleration a=8.1m/s^2Speed of the motorcycle is v=a*tSolving v=a*t=72m/s for t we get

8.1 *t = 72t=72/8.1 =80/9 s ~8.889 s
