Question

) If a mass of a body is 120kg. Height of a
building is 4om. find the work done
by body by the body it granity is 10 m/sec​

Answer 1

Answer:

Work done= MGH

                 = mass x Gravity x Height

                 = 120 x 10 x 40

                  =         48000 Joule

Answer 2

Answer:

Work done is change in potential energy of the object. Here the assumption is that the force which lifts the body, balances the weight at all times, meaning which there is no linear velocity of the object during this motion.

All the work done by the force is reflected as the increase in the stored potential energy of the object. Potential energy is defined as a difference of potential energy between two reference points and

Explanation:

U2 - U1 = mgh = 10 * 10 * 5 = 500 N-m

So the work done =Change in potential energy= 500 Nm.
