A football player is preparing to punt the ball down the field. He drops the ball from rest and it falls vertically 1.0 m down onto his foot. After he kicks it, the ball leaves the foot with a speed of 15 m/s at an angle 52° above the horizontal. a. What is the magnitude of the impulse delivered to the ball, in kilogram meters per second, as he kicks it? An American football has a mass of 450g. b. At what angle, in degrees above the horizontal, is the impulse delivered to the football?
