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

Text Solution

Verified by Experts

The correct Answer is:
C
Percentage loss of energy=`(mgh_1-mgh_2)/(mgh_1)`
`=(h_1-h_2)/(h_1)`
`=((20-15)xx100)/((20))`
`1/4xx100=25%`
The initial and final velocity of the body are 0 and 0.
