Question

Two bodies of mass $1kg$ and $5kg$ are dropped gently from the top of a tower. At a point $50cm$ from the ground both the bodies will have same.

• A. motenentum
• B. kinetic energy
• C. velocity
• D. total energy

Answer 1

The correct option is C velocity

The correct option is C.

Explanation:-

A) Momentum, $P=mv$

Momentum can not be same because both of them posses different mass.

B) Kinetic energy, $K=\frac{1}{2}m{v}^2$

From the above $K\propto m$

Both are posses different mass, so kinetic energy is not same.

C) Velocity is same, because the gravitational acceleration on both of them possess the same velocity and free fall under the gravity is independent of the mass.

D) Total energy is also mass dependent.
