Q1Energy, Work and PowerFree sample

A weightlifter performs an exercise in which he raises a mass of $200\text{ kg}$ from rest vertically through a distance of $0.7\text{ m}$ and holds it at that height.

(i)

Find the work done by the weightlifter.

(ii)

Given that the time taken to raise the mass is $1.2\text{ s}$ , find the average power developed by the weightlifter.
