Determine the time it takes the rock to follow this path.  What is the speed and angle below the positive horizontal which the rock impacts the side of the volcano?

Kilauea in Hawaii is the world's most continuously active volcano. Very active volcanoes characterisitcally eject red-hot rocks and lava rather than smoke and ash. Suppose a large rock is ejected from the volcano with a speed of 29m/s29m/s and at an angle of 37∘37∘ above the horizontal, as shown in the figure below. The rock strikes the ground at an altitude of 20m20m lower than its starting point. Include units as appropriate below.
