A. Which statement is a valid description and explanation of the skier's motion based on evidence from the diagram?
The skier's speed decreases going down the hill because forces F1 and F2 are balanced and acting
perpendicular to the direction of the velocity, causing the skier to speed up.
b. The skier's speed increases going down the hill because forces F1 and F2 are balanced and acting
perpendicular to the direction of the velocity, causing the skier to slow down
c. The skier's speed increases going down the hill because forces F3 and F4 are unbalanced, with F3 acting in
the same direction as the velocity, causing the skier to speed up.
d. The skier's speed decreases going down the hill because forces F3 and F4 are unbalanced, with F4 acting in
the opposite direction of the velocity, causing the skier to slow down.
