Swimmers at a Water Park Have a Choice of Two

Question 55

Multiple Choice

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