A major leaguer hits a baseball so that it leaves the bat at a speed of 30.5 m/s and an angle of 35.4 above the horizontal. You can ignore air resistance.
1) What is the magnitude of the baseball's velocity when it returns to the level at which it left the bat?
2) What is the direction of the baseball's velocity when it returns to the level at which it left the bat?
