Two carts are connected by a loaded spring on a horizontal, frictionless surface. the spring is released and the carts push away from each other. cart 1 has mass m and cart 2 has mass m/3.
1) is the momentum of cart 1 conserved?
2) is the momentum of cart 2 conserved?
3) is the total momentum of carts 1 and 2 conserved?
4) which cart ends up moving faster?
5) if m=6 kg and cart 1 moves with a speed of 16 m/s, what is the speed of cart 2?

Avery hard rubber ball (m = 0.5 kg) is falling vertically at 4 m/s just before it bounces on the floor. the ball rebounds back at essentially the same speed. if the collision with the floor lasts 0.05 s, what is the average force exerted by the floor on the ball?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
