1. An Olympic diver drops from the 10 meter platform with an initial vertical velocity of 0.0 m/s. If the diver needs to clear the edge of the pool by 5 m, what was the horizontal velocity of the diver at the instant of takeoff? What was the horizontal velocity right before landing? (You may assume that the edge of the platform was directly above the edge of the pool.) 2. A long jumper leaves the ground at an angle...
