A string is wrapped around a cylinder of mass M and radius R. The string is pulled vertically upwards to prevent the centre of mass from falling as the cylinder unwinds the string. The tension in the string is A solid iron sphere A rolls down an inclined plane. While an identical hollow sphere B [...]
A solid iron sphere A rolls down an inclined plane. While an identical hollow sphere B of same mass sides down the plane in a frictionless manner. At the bottom of the inclined plane, the total kinetic energy of sphere A is.

A uniform pole of length L and mass M is pivoted on the ground with a frictionless hinge. The pole makes an angle θ with the horizontal. The moment of inertia of the pole about one end is 3 1 ML 2 . If it starts falling from the position shown in the accompanying figure, the linear acceleration of the free end of the pole immediately after release would be :
