A stone of mass 300g is released from rest from the top of a bulding of height 100m. Determine the kinetic energy gained by the stone when it is a quarter way down from the point of release.[g = 10 ms^-2]

750.0J

225.0J

75.0J

m=300/1000=0.3

mgh=0.3*10*100=300/4=75

P.E=mgh

where m=300g=0.3kg

h=3/4 * 100=75m=100-75=25m.

Then p.E=0.3*10*25=75j
