Study of moving bodies under the action of forces _______

A body moves from point A to B under the action of a force, varying in magnitude as shown in figure. Obtain the work done. Force is expressed in newton and displacement in meter.

The displacement of a body moving along a straight line is givne by S =bt^(n) where 'b' is a constant and 't' is time. For what value of 'n' the body moves under the action of constant force ? .

A body moves a distance of 20 m along a striaght line under the action of a force of 10N. If the work done is 100J, the angle between force and displacement vectors is

The displacement x of a body of mass 10 kg moving in one dimension under the action of a constant force is related to time by the equation t = sqrtx + 3 . Find the work done by the force in first 5 seconds.

_________ deals with the bodies which are at rest under the action of forces .
