I have a question regarding friction in rolling without slipping.
There is a disk that is being acted by a force at an angle. I am asked to find the acceleration of center of mass and angular acceleration. The problem specifies, āthere is friction between the disk and the ground, but the disk rolls without slippingā.
What does that mean? Does it mean I can ignore friction and use F as the only force producing torque? Does friction produce torque in this case?
Iāll leave a picture here:
