QULSTION 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 94.7 m/s and at an angle 63.3° above the horizontal, as shown in Figure. The rock strikes the side of the volcano at an altitude 29.2 m lower than its starting point. What is the magnitude of the rock's velocity at impact? Input your answer in m/s using 3 significant figures.
