(I) A 7700 -kg boxcar traveling 18 $\mathrm{m} / \mathrm{s}$ strikes a second car. The two stick together and move off with a speed of 5.0 $\mathrm{m} / \mathrm{s} .$ What is the mass of the second car?
In the railroad freight yard, an empty freight car of mass $m$ rolls along a straight level track at $1.0 \mathrm{m} / \mathrm{s}$ and collides with an initially stationary, fully loaded boxcar of mass 4.0m. The two cars couple together on collision. (a) What is the speed of the two cars after the collision? (b) Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at $1.0 \mathrm{m} / \mathrm{s} ?$
