A 0.280 kilgram puck, initially at rest on a friction less horizontal surface, is struck by a 0.205 kilogram puck that is initially moving along the x axis with a velocity of 2.00 m/s. After the collision, the 0.205 kilogram puck has a speed of 1.12 m/s at an angle of q = 56.3 degree to the positive x axis.
Find the velocity of the 0.280 kilogram puck after the collision.
Find the magnitude of the angle with respect to the x-axis.
Calculate the percentage of kinetic energy lost in collision.
