Question

A book that weighs 0.35 kilograms is kept on a shelf that’s 2.0 meters above the ground. A picture frame that weighs 0.5 kilograms will have the same gravitational potential energy as the book when it’s raised to a height of [HOW MANY]
meters.
(Use PE = m × g × h, where g = 9.8 N/kg. )

Answer 1

Answer:

so first calculate potential energy = 0.35×9.8×2

potential energy =6.86 joules

p. e. =mgh

so h =p. e./mg

so, h=6.86/0.5×9.8

so h= 1.4m
