if the static coefficient of friction in the ice rink between the floor and the skater's shoes is .2, how much pushing force can he supply before his boots will begin to slide?(the skater's mass is 120kg)

max friction force= .2*mass*g

He isn't a skater if he is sliding on his shoes.

The answer is 0.2*g*(120 kg) (in Newtons)
