θ = angle of the incline surface from the horizontal surface = 25⁰
μ = Coefficient of friction = 0.15
m = mass of the person = 65 kg
= kinetic frictional force acting on the person as he slides down
mg = weight of the person acting in down direction
= normal force by the incline surface on the person
