A 10.8-kg block is suspended from the ceiling of an elevator by a cord rated to withstand a tension of 150 N. Shortly after the elevator starts to ascend, the cord breaks. What was the minimum acceleration of the elevator when the cord broke?
The cable supporting a 2105 -kg elevator has a maximum strength of 23260 N.
What maximum upward acceleration can it give the elevator without breaking? Express your answer using
two significant figures.
A mass is suspended from the ceiling in an elevator by a heavy rope. The mass is 80 kg and the mass of the rope is 2 kg. If the breaking strength of the rope is 1000 N, what is the maximum acceleration of the elevator such that the rope will not break?
