This is a problem which, allegedly requires use of a trigonometric equation (so I've heard, but it is extra credit and thus no help beyond that will be given...) The problem: Libyan basketball player Suleiman Nashnush was the tallest basketball player ever. His height was 2.45 meters. Suppose Nashnush throws a basketball horizontally from a level equal to the top of his head. If the speed of the basketball is 12.0 m/s when it lands, what was the ball's initial speed? (Hint: Consider the components of final velocity...) I'm not really looking for the answer persay, but it is my understanding that I must seperate the vertical and horizontal components of the velocity, and I have no idea where to begin without being given an angle of displacement. Any help would be awesome, thanks in advance!
