Spheres A (mass 0.020 kg), B (mass 0.030 kg), and C (mass 0.050 kg), are each approaching the origin as they slide on a frictionless air table. The initial velocities of A and B are 1.50 m/s and 0.50 m/s. All three spheres arrive at the origin at the same time and stick together.
a) What must the x-component of the initial velocity of C be if all three objects are to end up moving at 0.50 m/s in the +x-direction after the collision?
b) What must the y-component of the initial velocity of C be if all three objects are to end up moving at 0.50 m/s in the +x-direction after the collision?
c) If C has the velocity found in parts (A) and (B), what is the change in the kinetic energy of the system of three spheres as a result of the collision?
