A 2.65 kg stationary package explodes into three parts that then slide across a frictionless floor. The package had been at the origin of a coordinate system. Part 1 has mass m1 = 0.500 kg and velocity (10.0i + 12.0j) m/s. Part 2 has mass m2 = 0.750 kg and a speed of 14.0 m/s, and travels at an angle 110o (counterclockwise from the positive direction of the x axis).

(a) What is the speed of part 3?

(b) In what direction does it travel?
