Two balls roll toward each other on a frictionless floor. The red ball has a mass of \(1.00\text{ kg}\) and a speed of \(3.00\text{ m/s}.\) The blue ball has a mass of \(5.00\text{ kg}\) and a speed of \(2.00 \text{ m/s}.\) If the balls stick together after the collision, determine the (approximate) final velocity of the balls.

A \(200\text{ kg}\) bumper car travels at \(8\text{ m/s}\) due east. It hits an identical bumper car traveling due north at \(8\text{ m/s}.\) If the two cars lock bumpers and stick together, what is the approximate resulting speed of the cars?

Ball \(A\) of mass \(2\text{ kg}\) is rolling on a frictionless horizontal floor at \(5\text{ m/s}.\) It collides head-on with ball \(B\) of mass \(3\text{ kg}\) which is initially at rest. If we let \(v_A\) and \(v_B\) denote the respective velocities of balls \(A\) and \(B\) after the collision, in which of the following situations are the linear momenta conserved?
Define the initial direction that ball \(A\) moves in as positive direction.
