Web4. A hockey puck has a mass of 1.0 kg. The coefficient of kinetic friction between the puck and ice is 0.15. A force of 2.6 N is applied horizontally to the puck to push it to the right. … WebIf the coefficient of static friction is 0.45, you would have to exert a force parallel to the floor greater than f s (max) = μ s N = ( 0.45) ( 980 N) = 440 N to move the crate. Once there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only 290 N f k = μ k N = ( 0.30) ( 980 N) = 290 N
