nor b.
Expert Solution

Step 1
You push a crate down a ramp at a constant speed then the potential energy decreases with constant kinetic energy.
Because as the crate is in uniform motion along the ramp when moving down the ramp, potential energy of create becomes less.
Therefore potential energy decreases when You push a crate down a ramp at a constant speed.
