Question 3 of 25 Map sapling learning Three crates with various contents are being pulled by a 3515-N force across a horizontal, frictionless roller- conveyor system. The group of boxes is accelerating on the conveyor at 1.686 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. 3515 N FRAGILE 2225 N 1374 N What is the total mass of the thre click to edit Number kg total What is the mass of each box? Number Number Number kg kg, kg Previous Check Answer e I Exit Next Hint

Explanation / Answer

let the total mass is mtot

Using second law of motion

3515 = mtot * 1.686

mtot = 2084 Kg

the total mass is 2084 Kg

Now ,for mass m1

1374 = 1.686 * m1

m1 = 814.9 Kg

the mass m1 is 814.9 Kg

for the mass m2

2225 - 1374 = m2 * 1.686

m2 = 504.7 kg

the mass m2 is 504.7 Kg

for m3

m3 = 2084 - 504.7 - 814.9

m3 = 764.4 Kg

the mass m3 is 764.4 Kg
