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

Options

  1. AExactly in the hand of the boy
  2. BOutside the truck
  3. CIn the truck behind the boy
  4. DIn the truck ahead of the boy

Correct answer

A. Exactly in the hand of the boy

Step-by-step solution

The truck is moving with a constant velocity v in the horizontal direction. When the man throws the ball vertically upward, the ball possesses the same initial horizontal velocity v as the truck and the man. Since there is no horizontal acceleration acting on the ball (ignoring air resistance), its horizontal velocity remains constant at v throughout the flight. The truck also continues to move with the same constant horizontal velocity v . Because both the ball and the truck cover the same horizontal distance in t
