Question

A 2 kg picture frame sits on a shelf at a height of 0.5 m. How much gravitational potential energy is added to the picture frame when it is lifted to a shelf of height 1.3 m? Acceleration due to gravity is g = 9.8 m/s2.

 A.10.23 J B.15.68 J C.25.48 J D.9.80 J

Answer 1

We know that:
Epg=mgΔh
Epg=2kg*9,8m/s²*0,8m
Epg=15,68J (b)

Answer 2
