A baseball slugger smacks a pitch and watches the ball fly into the bleachers for a home run, landing h = 5.5 m higher than it was hit. When visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf = 38.4 m/s at an angle θf = 34° below horizontal when caught. Assume the ball encountered no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial position. a)calculate the balls initial vertical velocity in m/s
