Momo with mass m is sliding down an inclined plane that makes an angle O relative to the horizontal. The coefficient of kinetic friction between Momo and the inclined plane is µk. Obtain an expression for Momo's acceleration along the incline. Assign a rotated Cartesian plane so that the acceleration is along the positive x-axis and the normal force is along the positive y-axis. The component of the weight parallel to Momo's acceleration is wx= mg Ф. The magnitude of the frictional force is f = Hk The normal force on Momo is n = mg Ф. With these expressions and applying Newton's second law, we arrive at an expression for Momo's acceleration: a = - Pk.
