i shoot the ball again and this time i let the cable slip or glide away in my hands in such a way that the tension shown is 100 N, let's neglect transformation of friction into heat, gravity and cable weight

how long will it take the ball to reach my horizontal?

what radius will have the cable when the ball is at my horizontal?

when the ball is at my horizontal going to my vertical what constant tension would show the dinamometer if when the ball reached my vertical had to have 10 m radius again by my having pulled the cable?

how long will it take it to reach my vertical?

the cable is pulled or let away by crancking the cable(rigid in this case) and the spinning axe in such a way that for every grade the axe spins the cable retracts or spands one meter or whatever necesary
