Question:

A 75-kg man stands on a spring scale in an elevator. During the first 3 seconds of motion from rest, the tension \(T\) in the hoisting cable is \(8300 \mathrm{~N}\). Find the reading \(R\) of the scale in newtons during this interval and the upward velocity \(v\) of the elevator at the end of the 3 seconds. The total mass of the elevator, man, and scale is \(750 \mathrm{~kg}\).
