A sled of mass m is given a kick on a frozen pond. The kick imparts to it an initial speed of 2.80 m/s. The coefficient of kinetic friction between sled and ice is 0.150. Use energy considerations to find the distance the sled moves before it stops.
______________m

The friction force F times the sliding distance X is the work done agaqinst friction. It equals the initial kinetic energy of the sled. The mass m will cancel out.
m*g*0.150*X = (1/2)*m*Vo^2
X = Vo^2/(0.3 g)= ___ m
