During a snowstorm an 83.3 kg student was standing on a concrete ramp, hoping not to slip on the slushy snow. The incline of the ramp was 19.5 degrees. What is the minimum coefficient of friction needed on this incline for the student to remain stationary, without sliding down? Create a free body diagram to assist you. The minimum coefficient of friction will be that coefficient at which the friction force equals the force acting on the student to move her down the incline. Remember, Ff = mu*N (where mu is the coefficient of friction and N is the force perpendicular to the surface).

During a snowstorm an 83.3 kg student was standing on a concrete ramp,
hoping not to slip on the slushy snow. The incline of the ramp was 19.5 degrees.
What is the minimum coefficient of friction needed on this incline for the
student to remain stationary, without sliding down?
Create a free body diagram to assist you. The minimum coefficient of friction
will be that coefficient at which the friction force equals the force acting on the
student to move her down the incline.
Remember, Ff = mu*N (where mu is the coefficient of friction and N is the force
perpendicular to the surface).
