i understand that, i misspoke. i wanted to know what mass to use, either the given mass, or a component of it to determine the acceleration.

do i use the actual mass times the friction force, or the normal force?

i drew the diagram. no answer to compare to, it's on webassign. do i have to determine the acceleration in the opposite direction based on the friction force?

Homework Statement a box given an initial speed of 3.0 m/s up a 19.0° inclined track. The mass of the box is 20 kg, and the coefficient of kinetic friction between sled and incline is 0.20. How far up the incline does the box move? Homework Equations F=ma, n=63.8N, mukN=12.76 The Attempt at...
