A ball with mass m = 0.100 kg and kinetic energy K₁ = 1.74 J collides elastically with a second ball of thesame mass that is initially at rest. After the collision, the first ball moves away at an angle of 0₁= 52.5° with respect to the horizontal, as shown in the figure. What is the kinetic energy of the first ball after the collision?
