Under what condition the distance and displacement of a moving object will have same magnitude?

A body moves in a circular path of radius 4m with a velocity of 6 ms^(-1) . Find the angular velocity.

A particle is moving along a circular parth of radius 5m with uniform speed of 5m/s. What will be the average acceleration when the particle completes half revolution ?

A body of mass 5 kg rotates in a circle of radius 2m with a uniform speed of 3 m/s calculate the centripetal force

What is the percentage change in the kinetic energy of a body when its momentum is halved ?

A particle is moving in a circle of radius 1.5m. Its speed is increasing by 180 rev/minute in one minute. What is it's linear acceleration ?

A particle moves along a circle of radius R. It starts from A and moves in anticlockwise direction. Calculate the distance travelled by the particle (a)from A to B (b)from A to C ©from A to D (d) in one complete revolution . Also, calculate the magnitude of displacement in each case .
