Question

The magnitude of the momentum of a cat is p. What would be the magnitude of the momentum (in terms of p) of a dog having three times the mass of the cat if it had a) the same speed as the cat b) the same kinetic energy as the cat? The magnitude of the momentum of a cat is p. What would be the magnitude of the momentum (in terms of p) of a dog having three times the mass of the cat if it had a) the same speed as the cat b) the same kinetic energy as the cat? The magnitude of the momentum of a cat is p. What would be the magnitude of the momentum (in terms of p) of a dog having three times the mass of the cat if it had a) the same speed as the cat b) the same kinetic energy as the cat?

Explanation / Answer

(P_{dog}/P_{cat} = 3mv/mv = 3/1) (0.5(3m)v^2 = 0.5mv_0^2;;; v= v_0sqrt3) (P_{dog}/P_{cat} = 3sqrt3)
