11. Sketch each situation, defining your vertical origin (y = 0 m) on your sketch. Then complete an energy flowdiagram and energy bar chart for each situation. Define the system if its not already done for youa) 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 - blockand EarthFlow 1-2O: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 moveEvent 2- the block has travelled 1 m along the ramp (it is still moving)System:Flow 1-20
