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 very small object with mass 8.20 * 10-9 kg and positive charge 6.50 * 10-9 C is projected directly toward a very large insulating sheet of positive charge that has uniform surface charge density 5.90 * 10-8 C>m2 . The object is initially 0.400 m from the sheet. What initial speed must the object ha

New Sellwood Bridge? Consider the issue of replacing the Sellwood Bridge in Portland, Oregon. The existing bridge has a free-fl ow capacity of 600 vehicles, and the private trip cost at this traffi c volume is $2. Given the equilibrium volume of 1,000 vehicles per hour, the private trip cost is $3. T
