The moment of inertia of a body does not depend on :

A body moves from A to B. The velocity of the body at A is u and at B is V. Time taken by the body to move is t: Write down the expression for acceleration ‘a’ of the body.

Velocity of a particle depends upon t as V = A + Bt + Ct^2 . If velocity is in m/s, the unit of A will be :
