Here is the problem which I am struggling on, please help me!
Problem: How many joules of potential energy does a 1.5 kg book gain when it is elevated 4 m? (Use the equation: Gravitational potential energy = weight x height. (PE = mgh) (Let g = 10 N/kg)).
Please give step by step solution with notes on concepts and equations being used.
