Answer» A locomotive of mass $m$ starts moving so that its velocity varies according to the law $v = k \sqrt{s}$ where $k$ is constant and $s$ is the distance covered. Find the total work performed by all the forces which are acting on the locomotive during the first $t$ seconds after the beginning of motion.
