An impulse ''I'' given to a body changes its velocity from `''v_(1) to v_(2)''` . The increase in the kinetic energy of the body is given by

A

`I(v_(1)+v_(2))`

B

`I(v_(1)+v_(2))//2`

C

`I(v_(1)-v_(2))`

D

`I(v_(1)-v_(2))//2`

Text Solution

Verified by Experts

The correct Answer is:
B

`DeltaKE=(1)/(2)m(v_(2)^(2)-v_(1)^(2)), J=Deltap=m(v-u)`
