## Homework Statement

a girl is skiing down a 35 degree inclined hill that is 120 meters long. She starts from rest and the snow has a coefficient of friction of .12.

A. Draw an FBD

B what is her acceleration

c. How much time dows it take her to travel the 120 meters

## Homework Equations

I am unsure on how to set up the question solution. I think it's CAE's that are used as well, but i am completely unsure.

## The Attempt at a Solution

ΣF= MA

ΣF=9.8(m)

vi= 0m/s

ΛD=120 m

vf = ?

t=?

a=?

120cos35= 98.29?

120sin35= 68.82?

If anyone could please help i would really appreciate it. If i can figure out how to set this problem up and solve it, i will be able to figure the other problems out. Thank you so much!

I don't think there's enough to solve it using cae's can i use the sin and cosine functions with the 35 degrees??
