4. . . ' A crow is flying horizontally with a constant speed of 2.70 m/s when it releases a clam from its beak (Figure 2 ) The clam lands on the rocky beach 2 10s later. Just before the clam lands, what is (a) its horizontal component of velocity, and (b) its vertical component of velocity? (c) How would your answers to parts (a) and (b) change if the speed of the crow were increased? Explain. Vo A FIGURE 2 5 . . . . ' A swimmer runs horizontally off a diving board with a speed of 2.62 m/s and hits the water a horizontal distance of 1.88 m from the end of the board. (a) How high above the water was the div- ing board? (b) If the swimmer runs off the board with a reduced speed, does it take more, less, or the same time to reach the water
