A diver runs horizontally off the end of a 3.0-m-high diving board with an initial speed of 1.8 m/s. Given that the diver's initial position is xi=0 and yi=3.0 m, find her x position at the time t = 0.25 s.

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.
