Is the collision in Example 10.7 elastic?

Data from Example 10.7

Pucks 1 and 2 slide on ice and collide. The inertia of puck 2 is twice that of puck 1 . Puck 1 initially moves at \(1.8 \mathrm{~m} / \mathrm{s}\); puck 2 initially moves at \(0.20 \mathrm{~m} / \mathrm{s}\) in a direction that makes an angle of \(45^{\circ}\) with the direction of puck 1 . After the collision, puck 1 moves at \(0.80 \mathrm{~m} / \mathrm{s}\) in a direction that makes an angle of \(60^{\circ}\) with its original direction. What are the speed and direction of puck 2 after the collision?
