The following measurements are recorded during a test run. Time taken to raise lift = 80s Current in motor = 6.25 A Voltage applied to motor = 240.0 V Mass of lift = 120 kg Height lift raised = 40m A) Calculate the energy needed to raise the lift B) Calculate the gain in potential energy of the lift after it has been raised C) Account for the difference between the values in (a) and (b)
