Rectilinear Motion 2. A 75 kg man stands on a spring scale in an elevator. During the first 3 secs of motion from rest, the tension T in the hoisting cable is 8300N. Find the reading R of the scale in N during this interval and the upward velocity v of the elevator at the end of the 3secs. The total mass of the elevator, man, and scale is 750kg. Ans. 830 N & 3.77m/s T=8300 N $+ 750(9.81) 7360 N R 75(9.81)= 736 N
