What will be the period of the displacement body of mass `m`?

A body moves in a circle of radius 10 m. what will be the distance travelled and displacement of body when it covers half the revolution?

A moving body of mass m and velocity 3 km/hr collides with a rest body of mass 2m and sticks to it. Now the combined mass starts to move. What will be the velocity of the combined mass ?

To displace body by 50m , 150J of work is done . What is the force applied in the direction of the displacement ?

A particle of mass 0.25 kg vibrates with a period of 2 s. It its greatest displacement is 0.4 m, its maximum velocity in m/s will be

A body of mass 0.2 kg performs linear S.H.M. It experiences a restoring force of 0.2 N, when its displacement from the mean position is 4 cm. Determine period of S.H.M when the displacement from the mean position is 1cm.

A body of mass m, moving with velocity mu collides elasticity with another body at rest having mass M. If the body of mass M moves with velocity V, then the velocity of the body of mass m after the impact is
