Homework Statement
They're two boxes on a ramp. Box 1 (on the bottom) is 8.60kg and has a coefficient of kinetic friction of .35 with an incline plane. Box 2 (on top of Box 1) is 1.3kg and has a coefficient of kinetic friction of .45 between the boxes. The two boxes are connected through a string with a pulley at the end of it. The incline of the ramp is 38 degrees. What is the acceleration of box 1 and box 2?
Homework Equations
F=ukFn
F=ma
The Attempt at a Solution
Well this is wrong, but I tried to find the frictional force first, so Ffr=.35(66.41N) = 23.24. I found the normal force by doing Fn=mgcos38. Then I just put that force for f=ma and found a. Then I did the same thing for box 2. But, my teacher said their accelerations would be the same. So I am a little bit confused on how to do this, I can't figure it out. Any help would be greatly appreciated. Thank you
