The momentum of a body is numerically equal to its kinetic energy. What is the velocity of the body in m/s?

A

`1 ms ^(-1)`

B

`2 ms ^(-1)`

C

`3 ms ^(-1)`

D

`4 ms ^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`KE = ( P ^(2))/( 2m ) = E ` (say)
As,` E = P implies P = 2m `
`implies v = 2 ms ^(-1)`
