Block A has a mass of 30 kg and block B a mass of 15 kg. The coefficients of friction between all surfaces of contact are `(mu_(S)=0.15` and `mu_(k) = 0.10)`. Knowing that `theta =30^(@)` and that the magnitude of the force F applied to block A is 250 N . Determine (1) acceleration of block A. (2) the tension in the rope.
