a student stands on an elevator scale at rest on the 64th floor of a building. the scale reads 847 N. As the elevator moves up the scales increases to 923 N, then decreases back to 847 N. the acceleration of gravity is 9.8m/s^2. Answer in units of m/s^2
What question? Do they want the rate of acceleration when it is accelerating? It accelerates and then continues at constant velocity.
