Question 7 (5 points)

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.

a. Draw the free-body diagram showing the forces acting on Blaine. (1 point)

b. Write the expressions for net force in the x- and y-directions. Be sure to tilt your axis along the incline. (2 points)

c. Calculate the net force and acceleration in the x- and y- directions. (2 points)
