1. The problem statement, all variables and given/known data The white ball (2kg) in the figure has a speed of 1.74 m/s and the yellow ball (1kg) is at rest prior to an elastic glancing collision. After the collision the white ball has a speed of 1.37 m/s. what angle does it scatter at if the yellow ball is scattered at 280 degrees? 2. Relevant equations mva=mvacos(@)+mvbcos(@) 3. The attempt at a solution 2(1.37)Cos(@)a+0.58Cos280 2.74Cos@+.10 =92 degrees I think I'm close, but not quite.
