A simple pendulum of length 20cm and of mass 0.1kg is pulled to one side through an angle `theta` and released.If its maximum velocity is `1.4ms^(-1)`,the value of `theta` is ?

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

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

Two simple pandulum whose lengths are 100cm and 121cm are suspended side by side. Then bobs are pulled together and then released. After have minimum oscillation of the length pendulum will be two be in phase again. ?

A particle is projected at an angle theta =30^@ with the horizontal, with a velocity of 10ms^(-1) . Then

A simple pendulum of length l and consisting of a ball of mass m is released from a position making an angle theta=cos^(-1) (0.8) with the vertical and strikes at its lowest position a block of mass M resting on a rough horizontal plane. If the coefficient of kinetic friction between the plane and the block is 0.2 find (a) How long the block will move along the plane, if the ball of the pendulum rebounds to an angle beta=cos^(-1) (0.9)A (b) The coefficient of restitution, use (M)/(m) =10 and 1= 1 m

A simple pendulum of length I and mass (bob) m is suspended vertically. The string makes an angle theta with the vertical. The restoring force acting on the pendulum is
