Question

A car moving with a speed of 40 kmph passes a stationary policeman at a certain instant. At the same instant the policeman starts on a motor cycle with uniform acceleration 2 kmph^2 and chases the car. At the instant when they are side by side the relative velocity of the motor cycle with respect to the car is(in kmph)

Answer 1

Answer:

When the car is moving with uniform velocity, then there is nil acceleration in the motion of the car.

Therefore, the total acceleration of the car is 0.
