D Look at the system shown in the figure above. Block C weighs 450 N and Block D weights 25.0 N. Once block D is set into a downward motion, it descends at a constant speed. (a) What is the coefficient of kinetic friction between block C and the table top? (b) A small dog, also of weight 45.0 N, falls asleep on top of block C. If Block D is now set into a downward motion, what is the acceleration (magnitude and direction)?
