Question

A 625 kg elevator is pulled upward by a cable that exerts a 7250 N force. What is the acceleration of the elevator?(Don't forget its weight)

Answer 1

The acceleration of the elevator is 1.8 m/s².

Step-by-step explanation:

Given that,

Mass of elevator = 625 kg

Tension = 7250 N

We need to calculate the acceleration

Using equation of balance

`T-mg=ma`

Where, T = tension

m = mass

a = acceleration

Put the value into the formula

`7250-625*9.8=625* a`

`a=(7250-625*9.8)/(625)`

`a=1.8\ m/s^2`

Hence, The acceleration of the elevator is 1.8 m/s².
