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 m/s, a constant force acts on the bead. Figure indicates the bead's position at times t0 = 0, t1 = 1.0 s, t2 = 2.0 s, and t3 = 3.0 s. The bead momentarily stops at t = 3.0 s. What is the kinetic energy of the bead at t = 10s?
