Question

A hockey puck on a frozen pond is given an initial speed of 19.0 m/s. If the puck always remains on the ice and slides 121 m before coming to rest, determine the coefficient of kinetic friction between the puck and ice.

An experimental rocket plane lands and skids on a dry lake bed. If it's traveling at 84.0 m/s when it touches down, how far does it slide before coming to rest? Assume the coefficient of kinetic friction between the skids and the lake bed is 0.720. d = m
