1. The problem statement, all variables and given/known data a 4.00-kg block is sliding up the plane on a 30 degree incline. If the coefficient of kinetic friction between the block and the inline is .700. What will be the acceleration of the block if a 50-N horizontal force pushes on the block? 2. Relevant equations 50 - mgsin(30) - Uk*mg*cos(30) = ma 3. The attempt at a solution I am getting answer 6.65 something whereas the correct answer is 4.40 m/s. I suck at this topic. This is the weakest point I would appreciate your help.
