Energy Skate Park activity Calculations with Conservation of Mechanical Energy using time graphs https:/phet.colorado.edu/en/simulation/energy-skate-park Estimate a location for the Skater on a track. calculate the speed of height of the Skater Predict energy distribution for tracks with and without friction. Without using the simulation. predict the answers to the following questions Directions 1. This graph below was made with the 50 kg Skater riding on the track shown. The Skater was initially positioned on the top left of the track. Without using the simulation, provide a prediction to the following questions Energy Graph oration O Time Speed Stick to Track XXXXXXXXXX VW Total . 8 2506 D Reference Height .

Provide the position on the ramp and the direction of travel. iii. b) The maximum height of the ramp is 4 m. Predict the skater's height at the associated positions marked (i, ii, iii, and iv) on the graph: iii . iv. c) The maximum speed of the Skater is 8.8 m/s. Predict the skater's speed at the associated positions marked (i, ii, iii, and iv) on the graph: 11 . iv d) Sketch what the graph should look like for the remainder of the graph (to 20s) for KE and PE. Be sure to clearly label the graph and provide distinction between KE and PE
