A puck of mass 0.5 kg approaches a second, similar puck that is stationary on frictionless ice. The initial speed of the moving puck is 2 m/s. After the collision, one puck leaves with a speed v₁ at 30° to the original line of motion; the second puck leaves with speed v₂ at 60°, as in Figure.

(a) Calculate v₁ and v₂.

(b) Was the collision elastic?
