1. A 5.3 g bullet leaves the muzzle of a rifle with a speed of 336 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.92 m long barrel of the rifle?

2. A shopper in a supermarket pushes a loaded cart with a horizontal force of 12 N. The cart has a mass of 29 kg.

(a) How far will it move in 10.0 s, starting from rest? (Ignore friction.)

(b) How far will it move in 10.0 s if the shopper places his 30 N child in the cart before he begins to push it?
