Question

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

• A. Momentum
• B. Kinetic Energy
• C. Velocity
• D. Total energy

Answer 1

The correct option is C

Velocity

All the other quantities depend on the mass of the object. But g (acceleration due to gravity) doesn't depend on mass.
And we know the equation,
$V^2=u^2+2as$
u=0 and a =g
Hence, $v=(2\ast g\ast s{)}^{-1/2}$
So the final velocity for both the bodies will be same as 'g' and 's' is same for both the bodies.
