hey guys, im having trouble on 1 problem on my physics homework and was wondering if someone can help me and get me started.

Homework Statement


A 63-kg person on skis is going down a hill sloped at 30° from the horizontal. The coefficient of friction between the skis and the snow is 0.19. What would be the magnitude of the acceleration?

i have no idea where to start, looked all around my physics book but cant seem to find anything, any help would be great. thanks

Start by drawing a free body diagram. What forces are present? Do you know Newton's second law? That MUST be in your textbook somewhere. Show us what you come up with.

Hi,

First: draw a diagram of the scene.
Second: mark on all the forces using arrows
Third resolve the forces either horizontally and vertically OR parallel and perpendicular to the slope

Hope that gets you started.

Cheers
