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 meters.

Answer 1

Answer:

Step-by-step explanation:

E p = m · g  · h

E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J

E p ( picture frame ) = 6.86 J  

( same gravitational  potential energy as the book )

6.86 = 0.5 · 9.8 · h

6.86 = 4.9  h

h = 6.86 : 4.9

h = 1.4 m

Answer: ... to a height of 1.4 m.
