If the KE of a body becomes four times its initial value, then the new momentum will be more than its initial momentum by,

A

`50%`

B

`100%`

C

`125%`

D

`150%`

Text Solution

Verified by Experts

`vec(p)=sqrt(2m(KE))`
`rArr (p_(2))/(p_(1))=sqrt((KE_(2))/(KE_(1)))=sqrt((4)/(1))=2`
`rArr (Delta p)/(p_(1))=(p_(2)-p_(1))/(p_(1))=1` or 100%
