An Olympic skier whose mass is 50 kg is moving at 25 m/s down a 20degree slope encounters a region of wet snow of coefficient of frictio Uk=0.55 which reduces her speed.

A) Sketch the problem and identify (draw) the forces for the skier moving down an incline.

B) Draw a force vector diagram for the skier.

C) Find the normal force acting on the skier.

D) Calculate the kinetic friction force acting on the skier using the coefficient of friction given above.

E) Write an expression for the net force acting along the incline(x direction) for the skier.

F) Find the acceleration of the skier.

E) Assess your answer.Did you get acceleration units? Does the acceleration have the right sign? Is it a reasonable size?
