Chapter 9, Problem 115(choose chapter or problem)
At time t = 0, force PI = (-4.00i + 5.00]) N acts on an initially stationary particle of mass 2.00 X 10-3 kg and force P2 = (2.00i - 4.00J) N acts on an initially stationary particle of mass 4.00 X 10-3 kg. From time t = 0 to t = 2.00 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 twoparticle system? (c) What is the kinetic energy of the center of mass at t = 2.00 ms?
