[QUOTE="Chandra Prayaga, post: 6067762, member: 6922"] Instead of just writing the equation, you should first think of the physics of the problem. Ask yourself the following questions: 1. What is your system? 2. What are the surroundings exerting forces on the system? 3. What is the total initial energy of the system? What are the different contributions to it? 4. What is the final energy of the system? 5. Is the initial energy equal to the final energy? If so, why? If not, why? 6. Can any external forces change the energy of the system? 7. What is the Work-Energy theorem? 8 How do you calculate the work done by the external forces? Once you answer these questions, the answer should become clear. [/QUOTE]
