The bob of pendulum of length l is pulled aside from its equilibrium position through an angle `theta` and then released. Find the speed v with which the bob passes through the equilibrium position.

The bob of a pendulum of length l is pulled aside from its equilibrium position through an angle theta and then released. The bob will then pass through its equilibrium position with a speed v, where v equals

The figure shows a pendulum of length l suspended at a distance x vertically above a peg. (a) The pendulum bob is deflected through an angle theta and then released. Find the speed of the bob at the instant (b) The pendulum is released when theta = 90^(@) . For what x (position of peg) will the pendulum complete the circle ? (c) The pendulum is released when theta = 60^(@) . what is the velocity of the bob as it passes position E.

A mass at the end of a spring executes harmonic motion about an equilibrium position with an amplitude A.Its speed as it passes through the equilibrium position is V.If extended 2A and released, the speed of the mass passing through the equilibrium position will be

A small circular coil with a mass of m consists of N turns of fine wire and carries a current of I. The coil is located in a uniform magnetic field of B with the coil axis orginally parallel to the field direction. a. What is the period of small angle oscilations of the coil axis around its equilibrium position, assuming no friction and no mechanical force? b. If the coil is rotated through an angle of theta from its equilibrium position and then released, what will be its angular speed when it passes through equilibrium position?

A simple pendulum of length 1m has bob of mass 100 g. It is displaced through an angle of 60^@ from the vertcal and then released. The kinetic energy of bob when it passes through the mean position is

A simple pendulum of length l and bob of mass m is displaced from its equilibrium position O to a position P so that hight of P above O is h . If is then released. What is the tension in the string when the bob passes through the through the equilibrium position O ? Neglect friction. v is the velocity of the bob at O
