Question

A car is moving down the road with a constant velocity of 20m/s. The car passes by a big billboard. There is a police officer ( motorcycle) at rest behind the billboard. It takes one second to start the motorcycle and start chasing the car. The motorcycle is accelerating at 2m/s^2. How long does it take for the police to catch up the car from the moment the motorcycle starts moving

Answer 1

if it takes t seconds after the cop gets going, then

20(t+1) = (1/2)(2)t^2
