Question

Consider the system shown in the figure below. Block A weighs 49.6 N and block B weighs 28.2 N. Once block B is set into downward motion, it descends at a constant speed.

magnitude m/s2 Consider the system shown in the figure below. Block A weighs 49.6 N and block B weighs 28.2 N. Once block B is set into downward motion, it descends at a constant speed. Calculate the coefficient of kinetic friction between block A and the tabletop. A cat, also of weight 49.6 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration?

Explanation / Answer

coefficient of friction=0.5685

accleration=3.55(approx)
