A small brick of mass 0.5 kg is placed on a rough plane which is inclined to the horizontal at an angle θ\thetaθ, where tanθ=43\displaystyle \tan \theta = \frac{4}{3}tanθ=34, and released from rest. The coefficient of friction between the brick and the plane is 13\displaystyle \frac{1}{3}31.
Find the acceleration of the brick.
