a bag of rice weighs 75 kg .calculate the height to which it should be raised so that its potential energy is 7500 j.

(given : g = 10 m/s^2)

note - the answer is 10 m.

p.e = mgh

7500=75*h{ mg =weight}

75h=7500

h=10

simple answer ....

As PE = mgh

7500=750*10*h

7500 = 750*h

h = 7500/750

h = 10 m...
