A .3-kg puck, initially at rest on a frictionless horizontal surface, is struck by a .2-kg puck that is initially moving along the x-axis witha a velocity of 2m/s. After the collision, the .2-kg puck has a speed of 1 m/s at an angle of Θ53 degrees to the positive x-axis. (a)Determine the velocity of the .3-kg puck after the collision. (b) Find the fraction of kinetic energy lost in the collision.
