WebFind the coefficient of kinetic friction for the skier if friction is known to be 45.0 N. Strategy. The magnitude of kinetic friction was given in to be 45.0 N. Kinetic friction is … WebIf the coefficient of static friction is 0.45, you would have to exert a force parallel to the floor greater than 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 ( ) would keep it moving at a constant speed. If the floor is lubricated, both ...
WebDec 8, 2024 · The formula for the force of friction states: F = μ N. F=\mu N F = μN. For the example, consider a wood block of 2-kg mass on a wooden table, being pushed from stationary. In this case, you use the static coefficient, with μ static = 0.25 to 0.5 for wood.
