1. How could you use 100 pounds of force to lift a 200 pound weight? Explain precisely, listing any necessary distances and details. (This will take some converting!) 2. How long would a ramp need to be in order to move 1500kg to a height of 30 meters using only 50 N of force? How much Work would be done in this scenario? 3. Power is measured in watts. Electrical power is measured in kilowatts. Electrical energy used is measured in kilowatt-hours. How is the cost of electrical energy in your home related to the electrical power you use? 4. How would you turn a lever into a catapult? 5. Explain why it might be harder to pull a cart up a ramp faster than it would be to pull it up slower. (Work itself does not factor in time, so what else will you need to consider?)
