(10 points) A retaining wall against a mud slide is to be constructed by placing rectangular concrete blocks of 0.8 m height and 0.2 m width side by side as shown on the right. The coef±cient of friction μ between the concrete blocks and the ground is 0.3. Assume that the densities of concrete and mud are ρ concrete =2700 kg/m 3 and ρ mud =1800 kg/m 3 . Determine the mud heights h at which: a. the blocks overcome friction and start to slide, b. the blocks will tip over. Continue with your answer on the back of this page if necessary.
