A circular turntable is oriented parallel to the ground, ie., its axis of rotation is perpendicular to the ground. A penny of mass m is placed at a distance R from the axis of rotation and starting from rest the turntable accelerates with a constant angular acceleration a. Assuming the penny doesn't slip,
1) At what time is the tangential acceleration equal to the radial acceleration?
2) What is the linear speed of the penny at this time?
3) the coefficient of static friction between the penny and the turntable is µ. At what time does the penny start to slip?

A solid cylinder is mounted above the ground with its axis of rotation oriented horizontally. A rope is wound around the cylinder and its free end is attached to a block of mass 76.0 kg that rests on a platform. The cylinder has a mass of 275 kg and a radius of 0.480 m. Assume that the cylinder can rotate about its axis without any friction and the rope is of negligible mass. The platform is suddenly removed from under...

Consider a turntable to be a circular disk of moment of inertia 0.142 kg⋅m2 rotating at a constant angular velocity 4.80 rad/s2 around an axis through the center and perpendicular to the plane of the disk (the disk's "primary axis of symmetry"). The axis of the disk is vertical and the disk is supported by frictionless bearings. The motor of the turntable is off, so there is no external torque being applied to the axis. Another disk (a record) is...

A circular annulus, of mass M, inside radius a and outside radius 2a, is given an angular speed w about an axis, through its center perpendicular to its plane, which is horizontal. It is then gently placed on a rough horizontal plane, the coefficient of friction being u. Show that the annulus will start rolling without slipping after a time (10aw/13ug). The experiment is repeated in a space craft on a circular orbit around the earth. State giving reasons, whether...
