A particle of mass, m, acted on by a force, F, moves in a straight line. Its acceleration, a, is given by Newtons Law: F = ma. The work, W, done by a constant force when the particle moves through a displacement, d, is W = F d. The velocity, v, of the particle as a function of time, t, is given in Figure 6.25. What is the sign of the work done during each of the time intervals: [0, t1], [t1, t2], [t2, t3], [t3, t4],[t2, t4]?
