Only the horizontal component of velocity of the ball remains unchanged. When the ball rises the vertical component of velocity keeps on decreasing. During this time the bus accelerates out under the ball. To the boy the ball appears to go over his head. The ball, therefore, falls behind him.

Explanation:

  • The assertion states that a boy facing forward in a moving bus throws a ball straight up. At the same instant, the bus begins to accelerate. The ball goes up and falls in front of the boy.

  • The reason given is that as the ball rises, velocity remains constant.

  • However, this reason is not correct as the velocity of the ball changes as it rises and falls due to the acceleration of the bus.

  • The correct reason for the ball falling in front of the boy is that as the bus accelerates forward, the ball retains its forward velocity while the boy and the bus move forward, causing the ball to land in front of the boy.

  • Therefore, Assertion (A) is false but Reason (R) is true.
