Two players hit an air hockey puck simultaneously. One player hits the puck with a force = 4.75 at an angle = 23.9. The other player hits the puck with a force = 7.35 at an angle = 67.3. If the puck has a mass = 36.0 , what is , the acceleration of the puck, and , the angle of the puck's motion? The friction between the puck and the table's surface is negligible.
