A top is a toy that is made to spin on its pointed end by pulling on a string wrapped around the body of the top. The string has a length of 66 cm and is wound around the top at a spot where its radius is 1.4 cm. The thickness of the string is negligible. The top is initially at rest. Someone pulls the free end of the string, thereby unwinding it and giving the top an angular acceleration...

A long string is wrapped around a 6.1-cm-diameter cylinder, initially at rest, that is free to rotate on an axle. The string is then pulled with a constant acceleration of 1.6 m/s2 until 1.3 m of string has been unwound. If the string unwinds without slipping, what is the cylinder's angular speed, in rpm, at this time?

A light string of total length L is wrapped completely around the axle of a spinning toy top. The radius of the axle is r and the rotational inertia of the top is I. The top is initially at rest and the axle is held vertically with respect to a horizontal table. At time t = 0 a force with constant magnitude F pulls the string outwards from the axle of the top, which causes the top to rotate. After...

A small, solid cylinder with mass = 20 kg and radius = 0.10 m starts from rest and rotates without friction about a fixed axis through its center of mass. A string is wrapped around the circumference of the cylinder and pulled using a constant force F. The resulting angular acceleration of the cylinder is 5.0 rad/s2.

A massless string is wound around a solid cylinder that has a radius of 0.27 m and a mass of 28.8 kg. The free end of the string is tied to a block of mass 4 kg which hangs straight down. At t=0, the cylinder is allowed to spin about an axis through its center and the block falls, unwinding the string. Assume that the cylinder spins without friction. What is the acceleration of the block?
