The question is about the elevator (lift) and a weighting scale...what is the force diagram on a person standing in the elevator on a weighting scale...1. when the elevator is going upwards? and 2. when the elevator is going downwards? How should i calculate the acceleration and the weight appear on the weighting scale if relative values are given?

Can anyone show me the force diagram and tell me how to do the calculatoins...thanks
