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

What will be the momentum of a body of mass 'm which is moving with a velocity

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 ?

What is the expression for kinetic energy of a body of mass 'm' moving with velocity 'v'.

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
