A football quarterback is moving straight backward at a speed of 1.5 m/s when he throws a pass to a player 19 m straight downfield. The ball is thrown at an angle of 29° relative to the ground and is caught at the same height as it is released. a) What is the magnitude of the initial velocity of the ball relative to the quarterback in m/s b) What angle above the horizontal does the intial velocity of the ball relative to the quarterback make? Answer in degrees
