Need help:Weighing yourself in the elevator-acceleration problem 1. The problem statement, all variables and given/known data If you stand on a spring scale in your bathroom at home, it reads 600N, which means your mass is 60kg. If instead, you stand on the scale while accelerating at 2 m/s^2 upward in an elevator, what would the scale read? a. 120N b. 480N c. 600N d. 720N 2. Relevant equations W=mg 3. The attempt at a solution So I asked my professor this question and he came up with some complicated answer that I didn't really understand. My own logic was that W=mg, W=60kg * (2m/s^2+9.8m/s^2), W=720N which is the correct answer. However, this is not the same steps the professor used which was something like F=N-W=ma and he did some subtraction work and somehow got 720N. So can somebody explain to me the correct way to solve this problem?
