Answer:

534.9 N

Step-by-step explanation:

The skier weight is his mass times gravitational acceleration g

W = mg = 103 * 9.8 = 1009.4 N

This weight can be divided into 2 components, one perpendicular and the other parallel to the 32-degree slope. The parallel component would equal to


Wsin(32^0) = 1009.4sin(32^0) = 534.9 N
