Part A = 3062 J

If the average book has a mass of 1.4 kg with a height of 22 cm, and an average shelf holds 29 books, how much work is required to fill all the shelves, assuming the books are all laying flat on the floor to start?

Part A = 8.075 m/s

Part B = 0.255 m

What is his speed as he lands on the trampoline, 2.2 m below his jump off point?

If the trampoline behaves like a spring with spring stiffness constant 7.1 * 10^4 N/m , how far does he depress it? Any depression of the trampoline from equilibrium is to be taken as a negative distance.

Part A = 1.84 m

Part B = 1.55 m

If your speed is 3.00 m/s when you start to slide, what distance will you slide before stopping?

If her mass is 20.0 kg, what distance d does she slide (i.e., how far does she move after the push ends)? Remember that the friction force is acting anytime that she is moving?

Part A = d = mg/k + L

Part B = k = 2mgh / (h – L)^2

How far below the bridge will Kate eventually be hanging, once she stops oscillating and comes finally to rest?

If Kate just touches the surface of the river on her first downward trip (i.e., before the firstbounce), what is the spring constant k?

Part A = 1.65 * 10^9 J

What is the total work done by the two tugboats on the supertanker?
