Question
A $35.0$ -ton railroad freight car collides with a stationary caboose car. They couple together and $27.0 \%$ of the initial kinetic energy is dissipated as heat, sound, vibrations, and so on. Find the weight of the caboose.
Step 1
Step 1: We know that the initial kinetic energy of the freight car is given by $\frac{1}{2}mv^2$, where $m$ is the mass of the freight car and $v$ is its velocity. Show more…
