A major leaguer hits a baseball so that it leaves the bat at a speed of 28.3 m/s and at an angle of 38.0° above the horizontal. You can ignore air resistance.
A) At what two times is the baseball at a height of 9.00 m above the point at which it left the bat?
B) Calculate the horizontal component of the baseball's velocity at each of the two times you found in part (a).
vh1,2 = _____ m/s
