1. The problem statement, all variables and given/known data In the diagram below are two blocks. Block A sitting on top of block B has a mass mA = 10.0 kg and is attached to the wall by massless string. Block B, mass mB = 35.0 kg, is pulled by a force F = 75.0 N. The surface under block B is frictionless. The coefficients of friction for block A and B are μs = 0.34 and μk = 0.17. (a) Determine the acceleration of block B. (b) Determine the tension in the string. 2. Relevant equations Fnet=ma Ffriction-mg*coefficient friction 3. The attempt at a solution For the first part i went fnet=ma Ft=(m1+m2)a+M*g*μk 75=45a+35*9.8*.17 a=41.68/45 a=.37 m/s^2 Not sure if i am doing this correct, the coefficient of static friction is confusing me, do i need it in this equation? Part B Fnet=ma Ft=Ffriction+Ffstatic Ft=.37*35*.17+35*.34*9.8 ft=118.82N (seems right not sure) I am not fully confident in my work an answers can someone tell me if idid this correct, i have no answers unfortunately given to me. Please tell me if i went wrong somewhere or not thank you!
