Question

What is the gravitational potential energy of a 2.0-kg book 1.5 m above the floor?

Answer 1

Answer:

Gravitational potential energy is 29.4 J

Explanation:

Data :

   Mass = m = 2 kg

   Height = h = 1.5 m

Applying Gravitational Potential formula

         U = mgh

      U = 2 × 9.8 × 1.5

      U = 29.4 J
