A baseball player at bat hits a ball to the outfield. The
baseball is hit when it is at a height of 1.60 m above the home
plate. The ball’s velocity the instant it is hit is 34.00 m/s at an
angle of exactly 54.00o above the horizontal. The ball
lands safely in the outfield. Assume that the entire baseball
ground is horizontal.
(a) What are the vertical and horizontal components of the
ball’s acceleration while it is in the...
