At a water park, two slides with straight slopes, A and B, start and end at the same elevation. Slide A has a more gradual slope than B. Neglecting friction, your speed at the bottom of the slide is
A) larger for A than for B.
B) larger for B than for A.
C) the same for A and B.
D) unknown; more information is needed to work out the answer.
