A disk of 1-kg mass and 0.2-m diameter has a 30 revolutions per minute angular speed in the air when it is lowered and then touches a flat ground with 0.1 static and 0.07 kinetic friction coefficients. Determine the time it takes for the disk to cover a 200 m distance. Requirement: Give brief explanation on important steps.
