a) How much work is done on the body?
W=F*s =(mg)s= 300*6=1800J
b) What is the potential energy stored in the body?
P.E=mgh=30*2*6=1800J
c) Comment on the two answers above.
Workdone on the body is equal to the potential energy stored in the body. Hence the workdone against
gravity is stored as the potential energy.
