A ball is thrown toward a cliff of height h with a speed of 30 m/s at an angle of 60 degree above horizontal. It lands on the edge of the cliff 4.5 second later. (Suppose that the ball arcs before landing perfectly on the corner of the cliff.)
(a) Determine how high is the cliff?
m
(b) Determine what was the maximum height of the ball?
(c) Determine what is the ball impact speed?
m/s
