A lift motor has to move a fully laden lift $4\mathrm{.}59m$ between floor $1$ and floor $2.$ The lift has a

mass of $2150kg$ and takes $2\mathrm{.}41s$ to move from floor $1$ to floor $2($ignore friction$).$ What is the

work done by the lift in joules? $($Assume that acceleration due to gravity is $9\mathrm{.}81\frac{m}{s^2}$; round

your answer to two decimal places; DO NOT include units$)$
