Two pucks, A and B, are on an air hockey table. Puck A is moving with an initial velocity of 5.5m/s Eastward and Puck B is at rest and East of Puck A. Puck A collides with Puck B. After the collision, Puck A moves at an angle of 5 degrees North of East with a velocity,vfa, and Puck B moves at an angle of 37degrees south of East with a velocity, vfb. The masses of Puck A and Puck B are 0.025kg and 0.050kg, respectively.
A) Find the final speed of both pucks (vfa=3.4m/s, vbf=2.6m/s) (Remember that momentum is a vector, so you'll have to use components to find the final speed)
B) The fractional change in the kinetic energy.
