For this problem basically answer 1-9 (choices are a-d) if possible there can be multiple answers for each problem. If any more instructions are needed the paper should be sufficient. Please help me with 1-9 :)

Conservation of Energy I The diagrams below (A, B, C and D) illustrate and describe four different situations. Examine each diagram and then answer the questions below the diagrams. A. A block slides down a hill. B. The block comes to rest A man when it collides with a swings on a No = 0 spring at the bottom of the rope. The hill. The final state is the rope is instant just before the block attached to hits the spring. The system the branch includes everything except of a tree. the spring. V F * 0 The system VF * 0 includes everything. Earth Earth C. D. The hand pulls on A ball is sitting against a compressed a string which is spring. Later the ball is fired towards a attached to a block. person who catches the ball. The system The block is includes everything except the catcher. 0 - Vf* 0 attached to a spring that is stretched the entire time. The Vo= 0 system includes everything except the hand. Earth Earth Determine which of the diagrams above (A, B, C or D) have: 1. positive initial gravitational potential energy 2. negative initial kinetic energy 3. positive final kinetic energy System Initial Energy + Work = Final Energy 4. positive initial elastic potential energy Ko+ Ugo +Uso +Einto + W = Kit Ugf TU of + Bintf 5. positive final elastic potential energy. ?? ? 6. positive work 7. zero work 8. positive final internal energy .
