Get started for freeA rubber ball is dropped onto a ramp that is tilted at 20°, as shown in FIGURE P4.59. A bouncing ball obeys the “law of reflection,” which says that the ball leaves the surface at the same angle it approached the surface. The ball’s next bounce is 3.0 m to the right of its first bounce. What is the ball’s rebound speed on its first bounce?
25. II FIGURE EX4.25 shows the angular-velocity-versus-time graph for a particle moving in a circle, starting from at . Draw the angular-position-versus-time graph. Include an appropriate scale on both axes.
Ships A and B leave port together. For the next two hours, ship A travels at in a direction west of north while ship B travels east of north at .
a. What is the distance between the two ships two hours after they depart?
b. What is the speed of ship A as seen by ship B?
Answer Problems 3 through 5 by choosing one of the eight labeled acceleration vectors or selecting option
5. At this instant, the particle is speeding up and curving downward. What is the direction of its acceleration?
