Question

A machine rises a load of 750 N through a height of 16 m in 5 s. the work done by machine is​

Answer 1

Answer:

We know that Work=F×s.

Here force is equal to 750 N and displacement is equal to 16 m.

Hence,

W=750×16=12000Joule.

Hence energy spent is 12000J.

Power=work/time

P=12000/5=2400W.

Hence, we need a power of 2400 Watt.

Hope it helps..

Answer 2

Answer:

12000 j

Explanation:

We know that Work=F×s.

Here force is equal to 750 N and displacement is equal to 16 m.

Hence,

W=750×16=12000Joule.

Hence energy spent is 12000J.

Power=work/time

P=12000/5=2400W.

Hence, we need a power of 2400 Watt
