Problem 4: A baseball slugger slams a pitch and watches the ball reach into the bleachers for a home run, landing h=5.5m
higher than it was hit. When visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf=35.1m/s
at an angle \theta f=28.5∘
below the 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. Part (b) Calculate the magnitude, in meters per second, of the vertical component of the ball’s initial velocity.
