A 0.384 kg puck, initially at rest on a horizon-
tal, frictionless surface, is struck by a 0.189 kg
puck moving initially along the x axis with
a speed of 2.7 m/s. After the collision, the
0.189 kg puck has a speed of 1.7 m/s at an
angle of 28 to the positive x axis.
Determine the velocity of the 0.384kg puck
after the collision.
Answer in units of m/s
