Question
As part of your acrobat training, after you decide that college isn't for you so you run off and join the circus, you are practicing pulling yourself up using a seat connected to rope that runs over a pulley. For simplicity, you can assume the rope and pulley are ideal (no mass, no friction, etc.). Call your mass plus the mass of the seat M. How hard do you have to pull on the rope so that you accelerate upwards at a rate A?

How hard do you have to pull on the rope so that you accelerate upwards at a rate A?Explanation / Answer
let the spring constant of the rope be k.so,
distance to be pulled=m(a+g)/k
