Now let's apply the center-of-mass equations to a simple one-dimensional system. Suppose a 2.0 kg cat and a 3.0 kg dog are moving toward each other along the x axis, heading for a fight. At a particular instant, the cat is 1.0 m to the right of the origin and is moving in the + direction with speed 3.0 m/s, and the dog is 2.0 m to the right of the origin, moving in the - direction with speed 1.0 m/s. Find the position and velocity of the center of mass of the two-pet system, and also find the total momentum of the system. Find the velocity of the center of mass at the instant described in Part A. Express your answer in meters per second.
