Question: Consider a system shown in figure 2, block A weighs 45 N and block B weighs 30 N. (a) Once block A starts from rest

Consider a system shown in figure 2, block A weighs 45 N and block B weighs 30 N. (a) Once block A starts from rest and moves to the right determine the acceleration if μ between block A and the surface is 0.2. Determine the distance traveled and its velocity after 0.5 seconds. (b) With μ =0.2, what should be the new weight of block B so that both blocks A and B will move with constant velocity? .
