Question

Three crates with various contents are being pulled by a 3695-N force across a horizontal, frictionless roller- conveyor system. The group of boxes is accelerating on the conveyor at 1.408 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. In In Im 3695 N FRACILE 2365 N 1401 N What is the total mass of the three boxes? Number kg "' total What is the mass of each box?

Explanation / Answer

a) Force = mtot * a

mtot = 3695 / 1.408

Total mass = 2624 kg

b) mass m1 = T / a = 1401 / 1.408 = 995 kg

net tension = 2365 - 1401 = 964 N

mass m2 = 964 / 1.408 = 685 kg

Total tension = 3695 - 2365 = 1330 N

m3 = 1330 / 1.408 = 945 kg
