Explain the question

A motorcycle cop is hiding behind a billboard. A speeding car passes him, traveling at 20 m/s.

The policeman begins chasing the speeder (starting from rest) at the same time that he passes the

billboard, accelerating at a constant rate of 2 m/s2.

Describe with words what you would observe if you were watching the motorcycle cop chase the

policeman.

Draw a motion diagram of the chase.

I - 11

Sketch position, velocity, and acceleration graphs of both vehicles. Plot the motion of both

vehicles on the same graph.

Use the kinematics equations to determine at what time and at what position the motorcycle

intercepts the car. Will the motorcycle have the same speed as the car at that point? How do you

know?
