Question

a light body and a heavy body have same linear momentum.which one has greater K.E.?

Answer 1

Momentum=\(m\times v\)
K.E=\(\frac{1}{2} m\times v^2\)
light body's momentum= heavy body's momentum
=> velocity of light body is greater than velocity of heavy body
so tell which one has the higher KE, you have the relation

Answer 2

M1>M2 and let p1 = p2 i.e when the momentums of the bodies are same
then K.E1/ K.E2 = M2/M1 i.e the lighter body will have more K.E than the heavier body.
