Hi everyone!
Im having a project and i need to estimate the return hight of a falling yoyo
The yoyo is built of two 120cm radius and 2cm long cylinders connected by another one with a radius of 2.5cm and 30cm long. It is droped from the height of 30m with a rope that's 20m long.
How can i estimate how high it will bounce back (in the first time)? I tried looking for friction coefficients online and i found mew=0.25 for nylon which is close enough, but how can i estimate the energy loss due to rope friction?
thanks for your help, i know its not an east one and I am tight in time (need it by tommorow and just now remembered this forum). I set on it with a couple of friends and couldn't figure out a way to calc it
