A 5kg block is placed on top of 10kg block. A horizontal force is applied to the 10 kg and the 5kg is tied to the wall. The coe. of kinetic friction between all surfaces is .20.
What is the tension of the string? and acceleration of the 2nd mass.
The Attempt at a Solution
I know how to do the rest. But I'm not sure with my eqtns. that I made from my Free body diagrams.
1)-T+fk1 = m1a
n1 = m1g
n2 = m2g
