1. An elevator weighing 15 kN starts from rest and acquires an upward velocity of 3 m/sec. in a distance of 6 m. If the acceleration is constant, what is the tension in the cable?

Question

2. A man weighing 70 kg is in an elevator moving upward with an acceleration of 2.5 m/sec2.

A. What pressure does he exert on the floor of the elevator?
B. What will be the pressure if the elevator is descending down with the same acceleration?

Answer 1

16.15 kN

Answer 2

An elevator weighing 980N attains an upward velocity of 3m/s in 3s following a uniform acceleration. The tension in the cable that supports the elevator is

Answer 3
