TOTAL MECHANICAL ENERGY
1) If a 15 kg object is 30 m above the ground and its total mechanical energy is 7000 J, determine its kinetic energy. Show all your equations and your work. Include correct units on your final answer.
2) If a 25 kg object is 40 m above the ground and its total mechanical energy is 11,050 J, determine its speed. Show all your equations and your work. Include correct units on your final answer.
3) If a 30 kg object is moving at 7 m/s and its total mechanical energy is 1,080 J, determine its potential energy. Show all your equations and your work. Include correct units on your final answer.
4) If a 50 kg object is moving at 30 m/s and its total mechanical energy is 51,900 J, determine how high it is above the ground. Show all your equations and your work. Include correct units on your final answer.
