Question

Part A - Practice Problem: I direction with speed 2.9 m/s. Find the position of the center of mass at this instant. 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 I 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 + 1 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. At the instant described, the cat decides to avoid combat. It quickly turns around and runs in the Express your answer in meters.
