Answer 2

Answer:

2666.67 watt

Explanation:

Given :

Mass m = 500 kg

Height h = 16 m

Time t = 30 sec

We know :

Work done = Δ P.E.

= > Work done = m g h

= > Work done = 500 × 16 × 10 J

For power :

Power = Work done / Time

= > Power = 500 × 16 × 10 / 30 watt

= > Power = 500 × 16 / 3 watt

= > Power = 8000 / 3 watt

= > Power = 2666.67 watt

Hence we get required answer!
