Q1. A 33.0 g bullet moving at 434 m/s strikes a 5.0 kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 295 m/s. How fast is the bag moving while the bullet exits?

Q2. A small, 303 {rm g} cart is moving at 1.50 {rm m/s} on an air track when it collides with a larger, 3.00 {rm kg} cart at rest. After the collision, small cart recoils at 0.890 {rm m/s}.What is the speed of the large cart after the collision?
