1. A machine has a steel shuttle that is moving along a fixed unlubricated steel rail pulled by an elastic shuttle cord, which is at an angle
The shuttle has a mass of 800g and is released when the elastic cord has 20N tension at an angle of 45 degrees.
I know how to solve the problem, but I do not know why friction does not play a role here.
