fk = Submit Part C Two players hit an air hockey puck simultaneously. One player hits the puck with a force F₁ = 4.15 N at an angle = 20.1°. The other player hits the puck with a force F2 = 5.45 N at an angle = 68.4°. (Figure 2) If the puck has a mass m₁ = 33.0 g, what is a, the acceleration of the puck, and y, the angle of the puck's motion? The friction between the puck and the table's surface is negligible.
