Question

Determine the amount of potential energy of a 5-newton book that is moved to three different shelves on a

bookcase. The height of each shelf is 1.0 meter, 1.5 meters, and 2.0 meters.

Answer 1

Yo sup??

potential energy is given by

U=mgh

mg=5 N

U1=5*1=5 J

U2=5*1.5=7.5 J

U3=5*2=10 J

Hope this helps.

Answer 2

Multiply 5 newton by each height. 1st is 5 joules, 2nd is 7.5, while 3rd is 10 joules.
