11PRACTICE PROBLEM
On top of a building, a ball is thrown towards a taller building a certain distance away. The initial velocity of the ball is 14.5 m/s at 21.5° above the horizontal. It hits the ground 3.8 s later. Ignore air resistance. What are the components of the ball's velocity initially and at the end of its trajectory?
