Asked Oct 13, 2019

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 *μ _{k}*.

**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 *μ*_{k} = 0.34. Treat down the incline as the positive direction.
