Chapter 4, Problem 72PQ
An observer sitting on a park bench watches a person walking behind a runner. Figure P4.72A is the motion diagram representing what this observer sees. To better reveal the changing distance between runner and walker, five observations (A through E) are shown on five separate lines in Figure P4.72B. To the observer on the bench, both the runner and the walker move to the right, and the gap between them widens. Draw the motion diagram of the runner from the reference frame of the walker.

An athlete crosses a 29 m wide river by swimming perpendicular to the water current at a speed of 1.1 m/s relative to the water. He reaches the opposite side at a distance 35m downstream from his starting point.
How fast is the water in the river flowing with respect to the ground in m/s?
A rugby player runs with the ball directly toward his opponent’s goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball’s velocity relative to the field does not have a positive x component. Suppose the player runs at speed 4.0 m/s relative to the field while he passes the ball with velocity relative to himself. If has magnitude 6.0 m/s, what is the smallest angle it can have for the pass to be legal?
A stone is thrown from the top of a tower 15m above ground level at time t = 0. At the instant of launch, the stone has a speed of u = 5.00 ms-1 and moves in projective motion at an angle of 30°. At t = 2.00 s, the stone is still above ground level.
What are the x- and y- components of the stones displacement relative to its launch point at time t = 2.00 s and what is the distance from the stones launch point at this time?
