Question

4. A bag of wheat weighs 75 kg. Calculate the height to which it should be raised so that its potential
energy is 7500 J. (Given g = 10 ms-2).​

Answer 1

Explanation:

we know that po e is mgh

therefore. mass is 7.5 (as mass is weight divide by g) g is 10 and pe is 7500

7500=7.5x10xh

7500=75xh

7500/75=h

100m=h
