Achild, who is 45 m from the bank of a river, is being carried downstream by the river's swift current of 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 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?

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
