Energy Conservation With Conservative Forces: Swimmers at a water park have a choice of two frictionless water slides, as shown in the figure. Although both slides drop over the same height h, slide 1 is straight while slide 2 is curved, dropping quickly at first and then leveling out. How does the speed v1 of a swimmer reaching the bottom of slide 1 compare with v2, the speed of a swimmer reaching the end of slide 2?
A. v1 > v2 B. v1 < v2 C. v1 = v2 D. The heavier swimmer will have a greater speed than the lighter swimmer, no matter which slide he uses. E. No simple relationship exists between v1 and v2.
