Question

calculate the height of an object following from the tall building of mass 150 kg and the potential energy is 450 J​

Answer 1

As we know that PE= mgh (PE= Potential energy)

Given - mass= 150 kg and PE= 450J and we know that g= 9.8 m/sec². So by putting the values , we get

450 J= 150× 9.8× h

450 J= 1470 h.

h= 450÷ 1470

h= 0.306122449 m
