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 21.0m/s at an angle of 34.5 degrees above the horizontal. Let the upward be the positive y direction.

a) What is the y component of the ball's velocity?

b) What is the ball's direction of motion just before it is caught? Please don't just give answer, explain if you can.
