Hockey Puck A 110 g hockey puck sent sliding over ice is stopped in 13 m by the frictional force on it from the ice.
(a) If its initial speed is 5.0 m/s, what is the magnitude of the frictional force?
1 N
(b) What is the coefficient of friction between the puck and the ice?
2

Vf^1=Vi^2 + 2ad but a= force/mass, so

you can solve for force.

coefficent offriction:
frictionforce=mu*mg solve for mu.
