A hockey player hits a puck with his stick, giving the puck an initial speed of 5.0 m/s.
The puck slows uniformly and comes to rest in a distance of 20 m. What is the coefficient
of kinetic friction between the ice and the puck?

anonymous · Answer

By using the equation of motion:$$v ^{2}-u ^{2}=2as$$ 
where a=kg  and "k" is the coefficient of kinetic friction
on solving the equation, you will get the coefficient of kinetic friction

do you get it?
