Question

A box of mass 3 kg is lifted 1.5 m onto a shelf. Calculate the change in its gravitational potential energy. The gravitational field strength is 10 N/kg.

What’s the joules?

Answer 1

45J

Step-by-step explanation:

GPE = m x g x h

m= 3 kg

g= 10 N/kg

h= 1.5m

GPE = 3 x 10 x 1.5

GPE = 45 J
