Q1Energy, Work and PowerFree sample

A crane is used to raise a block of mass $50\text{ kg}$ vertically upwards at constant speed through a height of $3.5\text{ m}$ . There is a constant resistance to motion of $25\text{ N}$ .

(i)

Find the work done by the crane.

(ii)

Given that the time taken to raise the block is $2\text{ s}$ , find the power of the crane.
