Fill in the Blank: Potential Energy

A 0.50-kg sphere at the top of an incline has a potential energy of 8.0 joules relative to the base of the incline. Rolling halfway down the incline will cause the sphere's potential energy to be ______________.
 
Fill in the blank and explain why please.

Do you know the height of the incline? With the height h, you can calculate the PE of the sphere at the top of the incline, which is mgh. The PE of the sphere halfway down the incline would be mg(h/2).
