A 5.3 kg block rest on a level surface. The coefficient of static friction is , and the coefficient of kinetic friction is a horizontal force, X, is applied to the block. As X is increased, the block begins moving. Describe how the force of friction changes as X increases from the moment the block is at rest to when it begins moving. Show how you determined the force of friction at each of these times before the block starts moving, at the point it starts moving, and after it is moving. Show your work
