- If someone is riding in the back of a pickup thick and throws a softball straight backward, is it possible for the ball to fall straight down as viewed by a person standing at the side of the road? Under what condition would this occur? How would the motion of the ball appear to the person who threw it?An athlete crosses a 25-m-wide river by swimmingperpendicular to the water current at a speed of 0.5 m/srelative to the water. He reaches the opposite side at adistance 40 m downstream from his starting point. How fast isthe water in the river flowing with respect to the ground? Whatis the speed of the swimmer with respect to a friend at rest onthe ground?A motorboat is crossing a river that flows eastward at a speed of 5 kph. If the boat needs to maintain its northward course and a speed of 10kph relative to an observer standing on the river bank, what should be its velocity relative to the river?
