The problem is:
A block of mass m slides at a speed v along a horizontal, smooth table. It next slides down a smooth ramp, descending a height h , and then slides along a horizontal rough floor, stopping eventually.
If the zero level is a distance (2h/3) above the floor, what is the potential energy U of the block on the floor?
I'm confused about the zero level.
