Force is defined by the equation mass times the acceleration of the object. There are many different types of forces that act upon an object usually more than one at one time. In this problem, frictional force is the specific type of force that will be studied and defined. Frictional force is defined by the horizontal force along a rough surface acting upon an object moving along this rough surface. The frictional force is equal to the coefficient of kinetic friction multiplied by the normal force. The coefficient of kinetic friction is represented by k . while the normal force is equal to the mass of the object multiplied by gravity. Gravity is...
