3. Coal miners love physics, and in their spare time, they like to do physics experiments. One popular experiment involves using a sling shot to shoot lumps of coal into coal carts and seeing how far the carts move along the track as a result. One particular miner shoots a 5.0-kg lump of coal horizontally off a 10-m high ledge into a 90-kg cart waiting below, as shown. If the lump of coal has an initial speed of 30 m/s and the cart moves 0.80 m after the coal lands inside it, how much work did the friction between the cart and the track do on the cart? Also, what is the coefficient of kinetic friction between the cart and the track? Hint: you can assume that friction is the only force acting on the cart in the horizontal direction.

An iron ball with mass 180g is attached to a chain that is 1.2m long, suspended at an angle of 55 degrees . The iron ball is then released from this position and at the very bottom of its swing, it strikes a 450g wood block that is resting on a frictionless surface. To what angle does the iron ball rebound?

Two 3.0 g bullets are fired with speeds of 40.0 m/s and 80.0 m/s respectively. What are their kinetic energies? Which bullet has more kinetic energy? What is the ratio of their kinetic energies?
At the start of a race, a four-man bobsled team pushes their sled as fast as they can along a 50 m flat starting stretch. The net force that the four men together apply to the 325 kg bobsled is 964.079 N directed at 15 degrees below the horizontal. As they push, 60 N of kinetic friction opposes them. What is the speed of the sled right before the team jumps on the sled?

A 15-g bullet is shot vertically into an 2-kg block. The block lifts upward 8.0 mm (see the figure). The bullet penetrates the block and comes to rest in it in a time interval of 0.0010 s.
