Question

what is the initial momentum of the body?​

Answer 1

The moment of inertia, otherwise known as the mass moment of inertia, angular mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration. It depends on the body's mass distribution and the axis chosen, with larger moments requiring more torque to change the body's rate of rotation.

Answer 2

AnsWer

Initial momentum of a body is 200kgm/s and changes to 500kgm/s in 10s, on application of a force.
