Question
When a ball is thrown inside a moving bus, does its kinetic energy depend on the speed of the bus? Explain.
Solution
The kinetic energy of a ball thrown inside a moving bus depends on the speed of the bus because the kinetic energy is directly proportional to the square of the speed of the moving ball. The speed of the bus adds up to the speed with which the ball is thrown inside the bus. Hence, more the speed of bus, higher will be the ball’s kinetic energy.
