The figure below shows two boxes connected to each other by a light cord that passes over a pulley with negligible friction. The box of mass m = 10.0 kg hangs vertically while the box of mass m = 4.20 kg lies on an inclined surface with negligible friction. The surface is inclined at an angle of 39.0. (a) What is the magnitude of the acceleration of the 4.20 kg box (in m/s)? 6.03 Apply Newton's second law to each box one at a time, drawing a free-body diagram for each. What is true about the acceleration of each box? What is true about the tension force on each box? Can you find two equations that can be solved simultaneously for the acceleration and the tension? m/s (b) What is the tension in the cord (in N)? 37.7 Apply Newton's second law to each box one at a time, drawing a free-body diagram for each.
