A second baseman tosses the ball to the first baseman, who catches it at the same level from which it was thrown. The throw is made with an initial speed of 21.0 m/s at an angle of 35.0° above the horizontal. (Neglect air resistance.) (a) What is the horizontal component of the ball's velocity just before it is caught? m/s (b) How long is the ball in the air? s I am completely lost how to start this problem, I do not even know what a horizontal component is! Any help is appreciated. Can someone please tell me how to start this?
