Question

Two bodies of masses 1 kg and 5 kg are dropped gently from the top of a tower. At a point 20 cm from the ground, both the bodies will have the same
(a) Momentum
(b) Kinetic energy
(c) Velocity
(d) Total energy

explain the reason for the answer..​

Answer 1

Answer:

c

Explanation:

(a) Momentum cannot be the same because both of them possess different masses as you are aware that

           P= mv

(b)Same reasoning goes with kinetic energy due to different masses they will possess different kinetic energy and also in (d) the sum of both kinetic and potential energies are also different due to the variation in masses.

therefore (c) is clearly the correct answer because of gravitational acceleration both of them possess the same velocity and free fall under gravity is independent of mass

Answer 2

Answer:

your option is answer c

Explanation:

because earth's gravity pulls every body equally as it does not depend on the size shape or any other quantity
