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 end of slide 1 compares with v2, the speed of a swimmer reaching the end of slide 2? A) v1 > v2 B) v1 < v2 C) v1 = v2 D) No simple relationship exists between v1 and v2 because we do not know the curvature of slide 2.
