Question

A body weight 10KG is lifted to a height of 50 meter in 20 second. What is Power?

Answer 1

Solution :

• Given :

Mass = 10 kg

Height = 50 m

Time = 20 second.

Then,

Work done = m g h

⇒ 10 × 9.8 × 50

⇒ 4900 Joule

Now,

Power = Work done / time

⇒ Power = 4900 / 20

⇒ Power = 245 Watt

Hence, the power is 245 W.

Power = energy/time
=mgh/time

Power of the body is 245
