Suppose a large ship has a momentum of 1.55 × 109 kg⋅m/s.

(A) What is the mass of the large ship, in kilograms, if the ship is moving at a speed of 45 km/h?

(B) How much larger is the ship’s momentum than the momentum of a 1025-kg artillery shell fired at a speed of 290 m/s?

A person slaps her leg with her hand, bringing her hand to rest in 250 ms from an initial speed of 3.95 m/s

(A)What is the magnitude of the average force exerted on the leg, in newtons, taking the effective mass of the hand and forearm to be 1.7 kg?
