Energy, Work & Power Energy Problems Day #2

Example #1 Determine the amount of power required to pull the 100kg mass up the entire ramp if it takes 5 sec 10 sec

Example #2 You throw a 2.0kg object straight up in the air with a force of 30 N. If you apply the force over a distance of 75cm determine The change in gravitational potential energy of the mass The change in kinetic energy of the mass over that distance The total work done by you during the throw Compare your answers from a) and b) to your answer in c) what do you notice.
