A woman stands on a scale in a moving elevator. Her mass is 71.0 kg, and the combined mass of the elevator and scale is an additional 815 kg. Starting from rest, the elevator accelerates upward. During the acceleration, the hoisting cable applies a force of 9440 N. What does the scale read during the acceleration?

• physics -

tension= totalmass*(acceleration+ g)
solve for acceleration

now, given acceleration, scale reads mg+ma where m is the mass of the woman.
