Answer

Please see the work below.

Work Step by Step

We know that the frictional force is given as: $f=\mu N$ $\implies f=\mu (0.7M)g$ To find out the maximum acceleration, we equate this to $Ma$ $\implies \mu(0.7M)g=Ma$ This simplifies to: $a=\mu(0.7)g$ We plug in the known values to obtain: $a=(0.61)(0.7)(9.8)$ $a=4.2\frac{m}{s^2}$
