What is the potential energy of a 10 kg steel ball which has been raised vertically 9 m above the floor ?

A

441 joules

B

98 joules

C

90 joules

D

882 joules

Text Solution

Verified by Experts

The correct Answer is:
D
PE=Wh when W=10 kg and h=9 m
PE=(10)(9.8)(9)=10 kg x 9.8n x 9 m
=882 joules
