The acceleration of the block is $~3.7~m/s^2$
We can find the acceleration of the block: $\sum F = ma$ $mg~sin~\theta-mg~cos~\theta~\mu_k = ma$ $a = g~(sin~\theta-\mu_k~cos~\theta)$ $a = (9.80~m/s^2)~(sin~53^{\circ}-(0.70)~cos~53^{\circ})$ $a = 3.7~m/s^2$ The acceleration of the block is $~3.7~m/s^2$.
