Skater A, with unknown mass and unknown initial speed, bumps into stationary Skater B, mass 60.0 kg. After the collision, Skater A moves with speed 14.0 m/s at an angle of 36.9 from her original direction, while Skater B moves with speed 18.0 m/s at an angle of 53.1 from Skater As original direction. Both skaters move on the frictionless, horizontal surface of the rink
