A baseball is thrown from the roof of a 22.0 m tall building with an initial velocity of mag 12.0 m/s and directed at an angle of 53.1 degrees above the horizontal. (a) What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air function. (b) What is the answer in part (a) if the initial velocity is at angle of 53.1 degrees below the horizontal?
