Question

the momentum of a body is doubled, what eill beits kinetic energy

Answer 1

its kinetic energy will increase by 300%

Answer 2

K.E = 1/2 m v^2 where 'K.E.' is thekinetic energy of the body.Momentumis directly proportional to velocity. Ifthe momentum of an object is doubled, but its mass does not increase , then its velocity is doubled. IF momentum of a body is doubledthen its kinetic energy becomes 4times it's initial value
