Given the question: Q: Kilauea in hawaii is the world's most continuously active volcano. very active volcanoes characteristically eject red-hot rocks and lava rather than this? Read this paragraph and choose the correct option from the provided answers: Example 3.5 Calculating Projectile Motion: Hot Rock Projectile Kilauea in Hawaii is the world's most continuously active volcano. Very active volcanoes characteristically eject red-hot rocks and lava rather than smoke and ash. Suppose a large rock is ejected from the volcano with a speed of 25.0 m/s and at an angle 35.0 above the horizontal, as shown in Figure 3.40. The rock strikes the side of the volcano at an altitude 20.0 m lower than its starting point. (a) Calculate the time it takes the rock to follow this path. (b) What are the magnitude and direction of the rock's velocity at impact?. Choices: - greenhouse gases - carbon and smog - magma - smoke and ash A:
The answer is:
smoke and ash
