From the top of a tower of two stones, whose masses are in the ratio $1 : 2$ are thrown on straight up with an initial speed $u$ and the second straight down with the same speed $u$. Then neglecting air resistance :
- the heavier stone hits the ground with a higher speed
- the lighter stone hits the ground with a higher speed
- both the stones will have the same speed when they hit the ground
- the speed cannot be determined with the given data
The Correct Option is C

Acceleration
In the real world, everything is always in motion. Objects move at a variable or a constant speed. When someone steps on the accelerator or applies brakes on a car, the speed of the car increases or decreases and the direction of the car changes. In physics, these changes in velocity or directional magnitude of a moving object are represented by acceleration.
