If force is applied on the body in the direction of motion then ?

A body of mass 15 kg is moving with a velocity 20 m/s. Calculate the distance travelled by the body before stopping, if a force of 30 N is applied on the body in the direction opposite to the direction of motion.

Read each statement below carefully, and state, with reasons, if it is true, or false, During rolling, the force of friction acts in the same direction as the direction of motion of the CM of the body.

If a force F is applied on a body and it moves with a velocity V ,the power will be

A gardener moves a lawn roller through a distance of 50 m with a force of 100N. If the force is acting at an angle of 60° to the direction of motion, find the work done.

Two bodies of masses 10 kg and 20 kg respectively kept on a smooth, horizontal surface are tied to the ends of a light string. A horizontal force F = 600 N is applied to (i) A, (ii) B along the direction of string. What is the tension in the string in each case?

Two equal masses, one at rest and another moving undergo elastic QB lique collision. If one mass goes at an angle pi/3 .with its original direction of motion, what is the direction of motion of the other?

How can we change the speed and the direction of a moving body?
