Homework Statement
A 30-kg child on roller skates starts up a 10 degree incline at 15 km/h. Assuming she does not propel herself how far up the incline does she travel before stopping? Ignore frictional losses.
Homework Equations
F=ma W=mg
The Attempt at a Solution
I can do this problem if the force is given, but our book doesn't explain how to get force from mass, also would the 15 km/hr have anything to do with it? I've tried to work the problem out several times but I must be using the wrong value for force.
