A 0.408 kg puck, initially at rest on a horizontal, frictionless surface, is struck by a 0.0886 kg puck moving initially along the x axis with a speed of 3.14 m/s. After the collision, the 0.0886 kg puck has a speed of

2.14 m/s at an angle of 38◦ to the positive x axis.

Determine the velocity of the 0.408 kg puck after the collision.

Answer in units of m/s
