Two youngsters dive off an overhang intoa lake. Diver 1 drops straight down, and diver 2 runs off the cliffwith an initial horizontal speed v0. (a) Is the splashdown speed ofdiver 2 greater than, less than, or equal to the splashdown speed ofdiver 1? (b) Choose the best explanation from among the following:I. Both divers are in free fall, and hence they will have the samesplashdown speed.II. The divers have the same vertical speed at splashdown, butdiver 2 has the greater horizontal speed.III. The diver who drops straight down gains more speed than theone who moves horizontally.

Question
Two youngsters dive off an overhang into
a lake. Diver 1 drops straight down, and diver 2 runs off the cliff
with an initial horizontal speed v0. (a) Is the splashdown speed of
diver 2 greater than, less than, or equal to the splashdown speed of
diver 1? (b) Choose the best explanation from among the following:
I. Both divers are in free fall, and hence they will have the same
splashdown speed.
II. The divers have the same vertical speed at splashdown, but
diver 2 has the greater horizontal speed.
III. The diver who drops straight down gains more speed than the
one who moves horizontally.
