I am currently taking a 1st year introductory physics paper at university. I don't have a strong background in maths or science. 1. The problem statement, all variables and given/known data A skateboarder with a total mass of 65kg is skating on a half-pipe ramp, as shown above. When he is at the bottom of the ramp he is travelling at 12m/s. Using the principles of energy conservation, calculate how high (h) up the other side of the ramp he travels? (Assume a frictionless ride) I'm feeling stuck as to where to start. I guess this has something to do with inclined planes, and the skateboarder would reach the same height on the opposite ramp as the height that he started at, but as the problem doesn't give me the height, I don't know how to work it out. I'm wondering if kinetic energy would be relevant, as the formula is KE=1/2mv^2, and I have the mass and velocity? Help would be much appreciated!
