Question 24: Laws of Motion

Question

A man standing in a truck moving with constant velocity throws a ball vertically into air, ball falls

Accepted Answer

When the man throws the ball upward, the ball already has the same horizontal velocity as the truck. Since the truck is moving with constant velocity (meaning no horizontal acceleration), and assuming air resistance is negligible, the ball maintains its horizontal speed throughout its flight. This means:
Ã¢ÂÂ¢ In the reference frame of the truck, the ball moves straight up and then straight down.
Ã¢ÂÂ¢ Since thereÃ¢ÂÂs no extra horizontal motion relative to the truck, it will come back exactly to where it was thrown.
Thus, the ball will fall exactly into the hand of the boy.
The correct answer is: Option D $$	ext{Exactly in the hand of the boy.}$$
