Question: A ball is thrown toward a cliff of height h with a speed of 31 m/s at an angle of 60° above horizontal. It lands on the edge of the cliff 3.5 s later. (Assume that the ball arcs before landing perfectly on the corner of the cliff.)
Part A: How high is the cliff?
(in meters)
Part B: What was the maximum height of the ball?
Part C: What is the ball's impact speed?
(in meters/second)
If possible just a brief explanation how you got the answer?
