weight = mg
work = weight * distance
power = work/time
care to revise your answer?
A 30 kg water container is lifted to a height of 2 m in 1 minute. How much work is done in lifting the water container? How much power is exerted in the process?
I think it should be zero for both because the container has no horizontal displacement but that doesn't seem right...is it?
Thanks.

W = F*d = Mg*d = 30 * 9.8*2 =
P = W/t.
P = W/t.
