A motorcycle and a bus are moving with same momentum.Which of them has greater kinetic energy?Justify.

A car and a bus are travelling with the same velocity. Which has greater momentum ? Why?

Moment of inertia is the analogue of mass in rotational motion. But unlike mass, it is not a fixed quantity. The moments of inertia of two rotating bodies A and B are I_A and I_B lf ( I_A> I_B) and their angular momentum are equal. Which one has a greater kinetic energy? Explain.

A car and a lorry are travelling at the same velocity. Which has greater momentum?Why?
