Can you answer demonstration 3

Demonstration 3: The skateboarder now goes on the ramp shown on the right. Again, O friction is so small that it may be neglected. She glides down the ramp, up and down the hump and then up the other side. Indicate with an X on the diagram the maximum height she reaches on the way back up. Indicate with a Y on the diagram the point where her speed is the fastest. 1 Indicate with a letter from A to F on the diagram on the right the positions when her A. kinetic energy is maximum, B. kinetic energy is minimum, C. potential energy is maximum, D. potential energy is minimum, E. total energy is maximum, F. total energy is minimum. Only after you have made your predictions, use the Energy Skate Park: Basics simulation to make your observations. Select the correct ramp. Be sure that Friction is still set to None. Select both Bar Graph and Speed. Indicate your observations on the right in a different color ink. Home Interactive Lecture Demonstrations Kin.&Pot. Energy-Prediction Sheet Compare your observations to your predictions and explain any differences. Is kinetic energy conserved? Is potential energy conserved? Is total energy conserved? Explain why she is moving fastest at the point you observed
