1. The problem statement, all variables and given/known data What must be the applied force (25 degrees above the horizontal) in order to accelerate a block at 1.1 m/s^2, if the mass is 2kg and the coefficient of kinetic friction is .3? 2. Relevant equations F(net y)=Fn + Fav - W Ff = μ x Fn F(net x)=Fah-Ff 3. The attempt at a solution I've substitued the variables in and gotten these: 2(1.1) - xsin25 + 2(9.81) = Fn Ff = .3Fn 2(1.1) = xcos25 - Fn How do I find Fn?
