Problem 9P

CE Predict/Explain 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.

Solution 9P

Step 1 of 3

In this problem, for the two youngsters dive off an overhang into a lake and the diver 1 drops straight down and the diver 2 runs off the cliff with an horizontal speed , so we need to find (a) the splashdown speed of diver 2 is greater than, less than or equal to the splash down speed of diver 1, and (b) to choose the best statement among the following, given from the problem.
