1. A train has 90,000 j of potential energy at the top of a hill friction rob it of 18,000j on the way down how much kinetic energy remains
2. A Car driving down a long hill on the Highway has 20,000 J of Kinetic Energy, has 5,000J of Potential Energy left, and has lost 4,000 J due to friction. What was its Initial Potential Energy at the top of the hill?
3. A bicycle lost 200 J of Thermal Energy, has 1200 J of Kinetic Energy as it rolls down the trail, and still has 1600 J of Potential Energy before it hits the bottom! What is its TOTAL ENERGY?
4. If a Motorcycle had a Total Energy of 10,000 J, and 4,000 J of Potential Energy and 4,000 J of Kinetic Energy then how much Thermal Energy has it lost due to Friction?
