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 … WebP = 1646 N. Once the pallet starts moving, the coefficient of friction drops from its static value to its kinetic value. fk = µ kN = µ kmg. fk = (0.17) (600 kg) (9.8 m/s2) fk = 1000 N. But the forklift is still pushing with 1650 N of force. Thus we have a nonzero net force. ∑ F = P − fk. ∑ F = 1646 N − 1000 N. how much is the daily mirror uk
