1. A solid ball with a mass of 10kg and a radius or 0.3m starts from rest at the top of a 1.55m high hill. What is it's angular velocity at the bottom of the hill? What is it's linear velocity at the bottom of the hill?

2. A 6m long plank (m = 100kg) is held up by two wires (perpendicular to the lever arm). Wire T1 is at the far left end of the plank and wire T2 is at the far right end. If a 50kg person stands 2m from T1, what is the force in T1? what is the force in T2?

3. A 0.04kg wagon is pulled by a rope for a distance of 6.1m. The rope is at 32* above the horizontal and has a tension of 10N. If the wagon is pulled at a constant velocity, what is the work done by friction on the wagon? What is the work done by the rope on the wagon? what is the net work on the wagon?

4. A tired parent uses a rope to pull a sled (weight 50N) up a snow covered hill inclined at 18*. If the tension in the rope is 73N and the coefficient friction is 0.05, what is the acceleration?

5. A 20N applied force acts on a 6kg cart at 15* above the horizontal and causes the cart to accelerate at 2m/s2. What is the normal force? What is the coefficient of friction?

6. A 2kg toy car traveling north at 3m/s2 slams into a wall. What force does the wall experience?

7. Sam tosses a small rubber ball straight up into the air. If it in the air for a total of 4.2s. How high does the ball go?

8. In frustration a Physics student crumples up their paper and kicks it at 11m/s at 12° above the horizontal. How high does the ball go? What range does the ball travel?

9. Physics students visit the top of a building and toss metal balls horizontally off the roof. If the building is 34m high and the balls land 20m away from the base of the building, what is the final total velocity of the ball?
