1. The problem statement, all variables and given/known data Three Boxes, A, B, and C, are connected to each other using light vertical ropes, with box B hanging below box A, and C hanging below B. Call the tension in the rope connecting A and B "T_1" and that between B and C "T_2". A constant upward force F is applied to box A. Together, the boxes have a downward acceleration a. Gravity, as usual, pulls downwards, and take the positive direction as upwards. a) Make a labeled drawing. B) draw correct and complete free-body diagrams. c) give the equation(s) that come from the free body diagrams. You do not need to solve for anything. 2. Relevant equations F=ma 3. The attempt at a solution I am most concerned with C. For box a: F-Ft_1-F_g=m_a*a For box b: Ft_1-Ft_2-F_g=m_b*a For box c: Ft_2-F_g=m_c*a 1) my acceleration, a, is the same for all boxes 2) There is no normal force as the problem does not state that the boxes are on the ground or anything(?) 3) Should the mass for box c include the mass's of A+B??? Thank you.
