A ball of mass 2 kg and another of mass 4 kg are dropped together from a 60 feet tall building. After a fall of 30 feet each towards earth, their respective kinetic energies will be in the ratio of

Multiple Choice Options

A $\sqrt{2}:1$
B 1:04
C 1:02
D $1:\sqrt{2}$

Step-by-Step Verified Solution

From the question, as height is same for both balls, so their velocities on reaching the ground will be same. Hence in such case kinetic energy _ mass So, K . E 1 K . E 2 = m 1 m 2 = 1 2
