awesome, thanks. However the formula gSin(angle) - ugCos(angle) = a gives me a negative acceleration until i reach an angle of 15 degrees. Is there a way to calculate for the acceleration below 15 degrees? I drew this out as a free body diagram for an angle of 2 degrees but i don't not know...

Edit: Sorry, i just realized i posted this in the wrong section. Ok so I was assigned this project to compare accelerations of a 200g block on an inclined plane to that of a marble. My teacher also wanted me to derive formulas to solve acceleration for any given frictional force, mass, and...

1. A ball is thrown upward from the ground with an initial speed of 25m/s. At the same instant, a ball is dropped from rest from a building 15m high. After how long with the balls be at the same height? 2. The equation i had in mind was D=Vi(t) + 1/2 at^2 3. For this problem I believe that I...
