1. The problem statement, all variables and given/known data A 2kg block slides down a 3 m long ramp that is inclined at 40 degrees. The coefficient of friction is .2 What is the velocity when it hits the bottom of the ramp? 2. Relevant equations Kinetic = 1/2 mv^2 Potential = mgh Work of friction: Fnμ*(displacement) 3. The attempt at a solution 1/2mv^2 + mgh = 1/2mv^2 + mgh - Fnμ*(displacement) v = 8.237. I don't think that's right, because I didn't take into account the angle. What do I need to do?
