oh okay, so in that case... efficiency= output/input x 100% and then do 0.5=output/input .. and solve for height variables? is that where your leaning towards maybe? if so any suggestions on what the input and output is... my thought was input= Epi + Eki (at the top of the ramp.. Eki will be...

Thank you for the reply! The whole project was based on this skate board ramp stimulation https://phet.colorado.edu/en/simulation/energy-skate-park and asked questions about the potential energy and kinetic energy at different heights on the ramp in the stimulation without friction. In the last...

I have to design a track for a skate boarder that is 50% efficient (friction must be present) from the start of the skater's drop-in, to his furthest point along the track. My skater's mass will be 75kg efficiency=energy output/energy input x100% I am not really sure where to go next and how...
