Friction force in two books
WebSolution: On a flat surface, the normal force on an object is N = mg. Using this, we can calculate the force of friction as follows: F = μN F = μ mg Substituting the values in the equation, we get F = (0.400) (40.0 kg) (9.80 m/s 2) F = 156.8 N. The frictional force acting on the boat is 156.8 N. http://physics.bu.edu/~duffy/py105/Friction.html
