1. The problem statement, all variables and given/known data
A 30kg 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. 2. Relevant equations F=ma W=mg 3. 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.

So the weight is just m*g, which is 294.3 N?
The x component of mg would be 294.3cos10?
