A diver in Mexico dives off the top edge of a cliff 200 meter above the ocean at speed of 3m/s in the horizontal direction.
(a) Find how long will it be before he hits the water below?
(b) Compute the horizontal distance from the foot of the cliff to the point where he enters the water?
(c) Find the vertical and horizontal components of the diver velocity just as he enters the water?
