Application of Definite Integrals
... One force acting on a body as a function of position is given by F = 3x2 + 2x (Newton), G = 100 (Newton) and T = 100 – (2x + 20) sin 600 (Newton). If the object moves from x1 = 1m to x2 = 3m, find the work done by the force if the angle between the force and the direction of the displacement is: a) ...
