At time t= 0, force F1 = (-6.31i + 6.70j) N acts on an initially stationary particle of mass 3.21 × 10°3 kg and force F 2 = (2.69i - 4.74j) N acts on an initially stationary particle of mass 3.00 × 103 kg. From time t= 0 to t = 4.46 ms, what are the (a) magnitude and (b) angle (relative to the positive direction of the x axis) of the displacement of the center of mass of the two-particle system? (c) What is the kinetic energy of the center of mass at t = 4.46 ms?
