WebThe stacks of boxes shown in the figure above are inside an elevator that is moving upward. The masses of the boxes are given in terms of the mass M of the lightest box. Assume the elevator is moving at constant speed, and consider the bottom box in the stack that has two boxes of mass 2M. WebSolving for the force of tension is just using the fact that net force = ma. Finding the tension in the left rope as m (g + a), you get 30.576 N (which you got). The tension in the other rope should be m (g - a) = 47.04 N (you added instead of subtracting). What do you feel like you're missing? 7 comments ( 2 votes) Show more... Show more comments

WebA force is applied to block 1 (mass m1). (a) Draw a free-body diagram for each block. Determine (b) the acceleration of the system (in terms of m1, m2 and m3), (c) the net force on each block, and (d) the force of contact … WebA force is applied to two blocks in contact, as shown. Strategy Draw a free-body diagram for each block. Be sure to consider Newton’s third law at the interface where the two blocks touch. Solution Significance A → 21 is the action force of block 2 on block 1. A → 12 is the reaction force of block 1 on block 2. ph3 element
