Question

ii) A lighter object A and a heavier object B
are initially at rest. Both are imparted the
same linear momentum. Which will start
with greater kinetic energy: A or B or both
will start with the same energy?​

Answer 1

If light and heavy body have equal momenterm then lighter body will have higher kinetic energy, since its velocity have to make up for its lighter mass. The lightbody. If two objects have the same mass and the same momenterm they have the same kinetic energy.
