Two balls are moving along a frictionless table and collide. Ball 1 has a mass of .600 Kg, and ball 2 has a mass of .400 Kg. Before the collision, ball 1 is moving with a speed of 6.5 m/s at an angle of 38 degrees below the horizontal, and ball 2 is moving with a speed of 4.2 m/s at an angle of 53 degrees above the horizontal. Air restistance is negligable. If the collision is completely inelastic,
A.) What are the final speed and direction of Ball 1?
B.) What are the final speed and direction of Ball 2?
C.) What is the total kinetic energy of the system after the collision?
