In a gutball tournament against people half his age, a physics professor threw his 0.4-kg soccer ball at a kid throwing a 0.6-kg basketball. The balls collided in midair (see the figure), and the basketball flew off with an energy of 92.8 J at an angle θ = 29.9 degree relative to its initial path. Before the collision, the energy of the soccer ball was 100 J and the energy of the basketball was 112 J. At what angle and speed did the soccer ball move away from the collision?
