2D Conservation of Momentum using Air Hockey Discs and Unit Vectors
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 i cm/s and after the collision it is [4.79 i - 9.57 j] cm/s, what is the...
