block a weighs 45 n and block b weighs 25 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 0.1. determine the distance traveled and its velocity after 0.5 seconds. b. with μ = 0.1, what should be the new weight of block b so that both blocks a and b will move with constant velocity?
