A body executing `SHM` passes through its equilibrium. At this instant, it has

A particle is executing SHM . It passes through mean position at the instant t = 0 . At what instants the speed of it is 50% of its maximum speed?

The P.E. of a particle executing SHM at a distance x from its equilibrium position is

The P.E. of a particle executing SHM at a distance x from its equilibrium position is

What should be the displacement of a particle executing SHM from the position of equilibrium so that its acceleration becomes half of its maximum acceleration?

A horizontal spring-block system of mass 1kg executes SHM of amplitude 10 cm. When the block is passing through its equilibrium position another mass of 1kg is put on it and the two move together.

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
