Three crates with various contents are being pulled by a 3575-N
force across a horizontal, frictionless roller-conveyor system. The
group of boxes is accelerating on the conveyor at 1.578 m/s2 to the
right. Between each adjacent pair of boxes is a force meter that
measures the magnitude of the tension in the connecting rope.
Assume that the ropes and force meters are massless.
