A bead with mass 1.8 X 10-2 kg is moving along a wire in the positive direction of an x axis. Beginning at time t = 0, when the bead passes through x = 0 with speed 12 mis, a constant force acts on the bead. Figure 7-22 indicates the bead's position at these four times: to = 0, t1 = 1.0 s, t2 = 2.0 s

A physical pendulum consists of an 85-cm-long, 240-g-mass, uniform wooden rod hung from a nail near one end (Fig. 14-38). The motion is damped because of friction in the pivot; the damping force is approximately t proportional to d6/dt. The rod is set in oscillation by displacing it 15 from its equil
