1. At the highest point kinetic energy is minimum / maximum while the potential energy is minimum / maximum. 2. At the lowest point kinetic energy is minimum / maximum while potential energy is minimum / maximum.
3. Mass affects / does not affect the conservation of energy.
4. How much potential energy does the 60 kg skater have before she starts her ride, 12 m above the ground?
5. How much kinetic energy does a 60.0 kg skater have traveling with a velocity of 4m/s?
6. How fast must a 20. 0 kg skater travel to have a kinetic energy of 360 Joules?
7. How high must a 2 0 kg basketball be thrown so it has a potential energy of 160 3?
8. How fast must the 2.0 kg basketball be thrown upward to achieve the same potential energy of 160 J?
9. A 75 kg skater starts his skate with an initial speed of 0.0 m's, 8.0m above the ground Just before he reaches the 2 pts ground what will be his velocity?
10. In the above question, all the potential energy became kinetic energy. How much work was done by gravity?
