A lift motor has to move a fully laden lift 8.91 m between floor 1 and floor 2. The lift has a mass of 2150kg and takes 5.68 s 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 9.81 m/s2; round your answer to two decimal places; DO NOT include units)
