Question

Blaine steps onto a ski slope with an angle of 25°. There is a coefficient of kinetic friction of 0.15 between him and the ground. He has a mass of 65 kg.

Draw the free-body diagram showing the forces acting on Blaine.

Answer 1

θ = angle of the incline surface from the horizontal surface = 25⁰

μ = Coefficient of friction = 0.15

m = mass of the person = 65 kg

`f_(k)` = kinetic frictional force acting on the person as he slides down

mg = weight of the person acting in down direction

`F_(n)` = normal force by the incline surface on the person

the free body diagram showing the forces acting on the person is given as
