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 95.1 m/s and at an angle 39.1° above the horizontal, as shown in Figure. The rock strikes the side of the volcano at an altitude 21.3 m lower than its starting point. Calculate the time it takes the rock to follow this path. Input your answer in seconds using 3 significant figures. Vo = 25 m/s 35 -20 m
