1. The problem statement, all variables and given/known data A sled takes off from the top of a hill inclined at 6 degrees to the horizontal. The sled's initial speed is 12 m/s. The coefficient of friction between the sled and the snow is 0.14. Determine how far the sled will slide before coming to rest. 2. Relevant equations F=ma vFsquared=vIsquared + 2a(d) vf= velocity final vI= initial velocity a=accel. d=displacement. 3. The attempt at a solution Well I didn't get very far because I don't have enough variables, I need mass! I obviously need to find accelerating, what would my f=ma statement be? I thought it would be Fapp - Ffriction = ma........help?
