Question

Assertion(A): 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. Reason(R) : As the ball rises, velocity remains constant. *

A Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

B Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

C Both assertion (A) and reason (R) are true

D Both Assertion (A) and reason (R) are false.

Answer 1

Answer:

D

Explanation:

both assertion and reason are false

Answer 2

D Both Assertion (A) and reason (R) are false is the correct option

Explanation:

• Only the horizontal component of the ball's velocity remains constant. The vertical component of velocity continues to decrease as the ball rises.
• The bus accelerates out from under the ball during this moment. The ball looks to go over the boy's head.
• Changes in speed can alter the velocity of an object. A new direction has been chosen. The term "constant velocity" refers to an object travelling in a straight path at a constant speed. The position of the item at can be written algebraically as, and the slope of the line shows the object's speed.
• As a result, the ball falls behind him.
