Chapter 3, Problem 49P(choose chapter or problem)
(II) A child, who is 45 m from the bank of a river, is being carried helplessly downstream by the river’s swift current of \(\text {1.0 m/s}\). As the child passes a lifeguard on the river’s bank, the lifeguard starts swimming in a straight line (Fig. 3–46) until she reaches the child at a point downstream. If the lifeguard can swim at a speed of \(\text {2.0 m/s}\) relative to the water, how long does it take her to reach the child? How far downstream does the lifeguard intercept the child?
