Question

A person stands on the ground 60 m away from a cliff with a height h. They throw a ball toward the cliff with a speed of vb = 30 m/s and an angle of 60° above the horizontal. It lands on the top edge of the cliff some time later. How high is the cliff, and what is the ball's impact speed?
