Question

Consider an object on an incline where friction is present. The angle between the incline and the horizontal is θ and the coefficient of kinetic friction is μk.

a.)  Find an algebraic expression for the acceleration of this object. Treat down the incline as the positive direction.

b.) Calculate the acceleration, in meters per second squared, of this object if θ = 31° and μk = 0.34. Treat down the incline as the positive direction.
