1. Mt Taal is one of the most active volcanoes in the Philippines and active volcanoes normally emit red-hot rocks and lava rather than smoke and ash. Believe a huge rock is emitted from the volcano with a speed of 30.0 m/s and at an angle 40 above the horizontal. The rock strikes the side of the volcano at an altitude 25.0 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?
