A baseball player hits a home run, and the ball lands in the
left- field seats, y=7.70 m above the point at which it was hit. It
lands with a velocity of v= 39 m/s at an angle of 28 degrees below
the horizontal. The positive directions are upward and to the right
in the drawing. Ifnoring aie resistance, find the magnitude and the
direction of the initial velocity with which the ball leaves the
bat.
