.

The coefficient of kinetic friction is equal to the force of kinetic friction divided by   a. the normal force b. the weight of the object c. the mass of the object d. the acceleration of the object     Why is static friction more complex in analysis than kinetic friction? a .Because its magnitude and direction can vary b. Because it is invisible c. Because it does not depend on the normal force d. Because it depends on the kinetic friction
