Let's consider friction now: Run this simulation again with μk > 0. Set the value for μk that is similar to the value you found from your Lab 6 (which should have been between 0.2-0.8). Include a screenshot of your setup when the object is at the bottom of the ramp. Is the total energy the same at the beginning as it is at the end? What is the percent difference in this case? Please show your calculations! If you look at each picture, one is lower on the ramp and then once the uk is 0.4. I need to find out what the total energy is at beginning and at the end.
