A 25-kg mass is suspended 4 meters above the ground. Find its potential energy. Show your work, and use the
rules of significant figures when giving your answer
Potential energy due to gravitation = mass x gravity x height = 25 x 9.8 x 4 = 980 Joules Since the height is given to just 1 significant figure, the result should be given to 1 significant figure also. Answer = 1000 Joules.
