Momo with mass m is sliding down an inclined plane that makes an angle Φ relative to the horizontal. The coefficient of kinetic friction between Momo and the inclined plane is μ_k. 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 w_x = mgBlank 1Φ.

The magnitude of the frictional force is f = μ_kBlank 2.

The normal force on Momo is n = mgBlank 3Φ.

With these expressions and applying Newton's second law, we arrive at an expression for Momo's acceleration:

a = Blank 4 ( Blank 5 - μ_kBlank 6 )
