2D Conservation of Momentum Example using Air Hockey Discs (13:27)
A 28.8 g yellow air hockey disc elastically strikes a 26.9 g stationary red air hockey disc. If the velocity of the yellow disc before the collision is 33.6 cm/s in the x direction & after the collision it is 10.7 cm/s at an angle 63.4° S of E, what is the velocity of the red disc after the collision? This is an AP Physics 1 topic.
