Question

A boy sitting in a bus moving at a constant velocity throws a ball vertically up in the air. The ball will fall:

• A. in the bus in front of the boy
• B. in the bus on the side of the boy
• C. outside the bus
• D. in the hands of the boy
• E. in the bus behind the boy

Hint:

In cases of relative motion, consider the reference frame of the observer to analyze the motion of objects.

Answer 1

The Correct Option is D

Step 1: The bus is moving with constant velocity, and the boy inside the bus throws the ball vertically. From the reference frame of the bus, the ball will appear to move vertically upward. 
However, from an external observer's frame (e.g., outside the bus), the ball will have both a horizontal and vertical velocity. 
Since the ball's horizontal velocity matches that of the bus, it will fall back in the hands of the boy.
