Acceleration of the center of mass? Do u mean I'll have to solve it using kinematics equations?
Before pure rolling occurs, what happens to the disk actually? slipping+rolling? i couldn't imagine how smth slip and roll at the same time. anything to help me picture that?
I have attempted to solve this question and I got stuck at the last part. Here you go.
A uniform solid disk is set into rotation with an angular speed X about an axis through its center. While still rotating at this speed, the disk is placed into contact with a horizontal surface and...
A particle of mass m and charge q moves at high speed along x axis. It it initially near x=-infinity and it ends up near x=+infinity. A second charge Q is fixed at the point x=0, y=-d. As the moving charge passes the stationary charge, its x component of velocity does not change appreciably, but...
