## Question:

A box slides down a 30.0° ramp with an acceleration of 1.20 m/s^2. Determine the coefficient of kinetic friction between the box and the ramp.

The coefficient of kinetic friction between the box and the ramp is 0.71.

Given data:

The angle of inclination is, .

The acceleration of box is, .

The frictional force acting on the box is,

Here, is the coefficient of kinetic friction and N is the normal force.
