Question

An 850 kg elevator is accelerating upwards at 3.0 m/s2. Calculate the tension in the cable.

Answer 1

10880N

Step-by-step explanation:

We are given that

Mass of elevator, m=850 kg

Acceleration,
`a=3m/s^2`

`g=9.8m/s^2`

We have to find the tension in the cable.

We know that

When elevator is accelerating upward then tension in the cable

`T=m(a+g)`

Using the formula

`T=850(3+9.8)`

`T=10880N`
