Who was the first person to observe a sign of molecular motion?

sled of mass m is given a kick on a frozen pond. The kick imparts to it an initial speed of 1.90 m/s. The coefficient of kinetic friction between sled and ice is 0.110. Use energy considerations to find the distance the sled moves before it stops.
