A rubber puck, initially travelling at 39 km/h, is sliding along an icy surface. How long (in seconds) would it take the puck to come to a complete stop if the coefficient of kinetic friction between the puck and the ice is 0.2?

The opposing force is F=μN=μmg
Acceleration opposing motion a= F/m = -μg
Initial velocity = v0 = 39 km/h = ? m/s
Final velocity, v1 = 0 m/s
Using
v1=v0*t+(1/2)at²
Solve for t.
