A man standing in a truck moving with constant velocity throws a ball vertically into air, ball falls
Options
- AExactly in the hand of the boy
- BOutside the truck
- CIn the truck behind the boy
- 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
