By raising the height of the ski jump hill
are you sure
Yes, I am sure. Increasing the height of the ski jump hill will increase the potential energy of a ski jumper as they have a greater vertical distance to accelerate against gravity before taking off.
The diagram shows a skateboarder.
At which location on the ramp does the skateboarder have the highest potential energy?

I apologize for the confusion. The highest potential energy for the skateboarder would be at point Z. The potential energy of an object is the highest at the highest point of its motion, which in this case is point Z on the ramp.
its w
I apologize for the incorrect response earlier. You are correct, the highest potential energy for the skateboarder would be at point W. At point W, the skateboarder is at the highest point of the ramp, and therefore has the highest potential energy.
