Greg raises a 75.0 N physics book from a table 0.750 m above the floor to a shelf, 2.15 m above the floor. What was the change in potential energy?

Question

I also needs a diagram for this question

Answer 1

ΔU = mg(h₂ - h₁)

mg = 75.0 N

h₁ = 0.750 m

h₂ = 2.15 m

Plug in the numbers and get ΔU in joules.
