1. The problem statement, all variables and given/known data Mass m1=26.1 kg is on a horizontal surface, connected to mass m2= 5.50 kg by a light string as shown. The pulley has negligible mass and no friction. A force of 197.7 N acts on m1 at an angle of 33.3 deg. The coefficient of kinetic friction between m1 and the surface is 0.233. Determine the upward acceleration of m2. 2.44 m/s^2 2. Relevant equations a1 = a2 T1 = T2 T1 = Fcos(theta) - Frictionforce Friction force = uk(Normal Force) Normal Force = weight - Fsin(theta) 3. The attempt at a solution I'm actually looking at this problem again since I first did a week ago and I don't have the sheet I worked it out on with me right now, but using the equations I wrote above keeping in mind that T1=T2 I pretty much worked the whole thing out, however when I entered it into the online homework system I got it wrong no matter what I did I just couldn't get it. Can someone help me out with what I'm doing wrong? By the way I know what the answer is, but I just no how you would go about getting to it, I step-by-step run down through the problem would be helpful.
