11. Sketch each situation, defining your vertical origin (y=0 m) on your sketch. Then complete an energy flow diagram and energy bar chart for each situation. Define the system if its not already done for you a) You have a small 0.2 kg block attached to a string. You are controlling the block's motion using the string. While raising the block 1.2 m over 1.7s, the speed of the block goes from 1.1 m/s to 1.5 m/s. System - block and Earth E+W-E. Flow 1-2 b) You release a block from rest at the top of a 2 m ramp. There is friction between the ramp and the block. Event 1-the block begins to move Event 2-the block has travelled 1 m along the ramp (it is still moving) System: O 0
