Question

Find the power exerted when a 10 N rock that you lift 50 m straight up in 2 seconds?

Answer 1

Answer:250kgm/s

Explanation:Power is defined as the rate of doing work.

Which means;

Power=workdone/time

But workdone =force * distance.

F=10N

D=50m

t=2s

So therefore ,

P=10*50/2

P=250kgm/s
