Question

a book has a mass of 0.95kg is held 2.3m above the ground. determine the gravitational potential energy of the book

Answer 1

Answer:

PEgrav = 21.4J

Explanation:

Use the gravitational potential energy formula

m= 0.95kg h=2.3m g= 9.8 N/kg

PEgrav = m *• g • h

PEgrav = 0.95kg * 9.8N/kg * 2.3m

PEgrav = 21.4J
