Nicholas Gonzalez · Answer 1

175J of the converted energy would be potential.

To reach this conclusion, look at your diagram.

For this example we will look at the one I was given.

To the left you are given the starting energy and to the right is one of the resulting energies, in this case I got friction.

Subtract one of the resulting energies from the starting energy and you got ur answer: 250J - 75 = 175J

Ms. Congeniality · Answer 2

If she is at the top of the half pipe, then there is no where else to go but down. Therefore, all of the skateboarders energy is potential.
