Problem

A golf ball of mass 0.045 kg0.045\,\text{kg} is struck so that it travels straight downward along the line x=+0.80 mx = +0.80\,\text{m} with a constant speed of 20 m/s20\,\text{m/s}. At the instant it leaves the club face the ball’s yy-coordinate is +3.0 m+3.0\,\text{m}. Neglect air resistance and model the ball as a point particle. (a) Determine the magnitude of the ball’s angular momentum about the origin at the instant it leaves the club face. (b) After 0.050 s0.050\,\text{s} of flight, calculate the magnitude of the ball’s angular momentum about the origin. (c) State whether the magnitude of the angular momentum is increasing, decreasing, or remaining constant as the ball continues its downward motion. Provide a brief explanation based on the geometry of the motion.
