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.
q1: Is the splashdown speed of diver 2 greater than, less than, or equal to the splashdown speed of diver 1?
q2: Choose the best explanation from among the following: The diver who drops straight down gains more speed than the one who moves horizontally., The divers have the same vertical speed at splashdown, but diver 2 has the greater horizontal speed. , or Both divers are in free fall, and hence they will have the same splashdown speed.
