Swimmers at a water park have a choice of two frictionless water slides, as shown. 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 of a swimmer reaching the end of slide 1 compare with , the speed of a swimmer reaching the end of slide 2?

v1 > V2

v1 < V2

v1 = V2

There is no simple relationship between v1 & V2
