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.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
