Elastic force of the rope when lifting the lift Fн = 4,0 KH. What work will be done by the elastic force when lifting the elevator to a height of h = 20m?
The work is found by the formula
A = F * S
Instead of S, we will use h, because both the path
Now we just have to substitute the values of force and path, but first we translate kN into N, and we get 4000 N
A = 4,000 * 20 = 80,000 (J)
Answer: A = 80,000 (J)
