A 55 kg passenger is standing on a weight in an elevator. The weight is measured in newtons (N). At first the lift is at rest, but then the cabin starts to move vertically, and the speed increases from 0 m / s to 8 m / s during 5 s. Assume constant acceleration.a) What shows the weight (in newtons) when the lift is at rest? b) What is the acceleration of the lift?
