Question

2 An elevator weighing 5,000 kg is moving
in upward direction & The tension in the
supporting cable is 50,oooN. Find the
upward acceleration. How far does it
rise in a time of 10 sec starting
from rest?​

Answer 1

Answer:

The elevator of 5000kg is moving up

Force applied by gravity (Fg) = 5000 × 10 = 50000.

It is given that tension(T) in support cable is 50000

So, no external force is applied acceleration is 0

Proof :- Fnet = T-mg = 50000 - 50000 =0

We know that Fnet = ma.

So, ma = 0 => a = 0

There is no acceleration, so displacement after 10s = 0.

Hope it helps.
