Tension Physics Problem?

Question

n elevator (cabin mass 570 kg) is designed for a maximum load of 2300 kg, and to reach a velocity of 3.5 m/s in 3 s. For this scenario, what is the tension the elevator rope has to withstand?

Answer 1

The total weight at max capacity is
2870*9.8 N
in the direction of motion
T-2870*9.8=2870*a

average a=3.5/3
T=2870*(3.5/3+9.8)
T=31474 N
