Question

To start off, I don't know where the three points are exactly. Also I assume the mass of the cord is its Force / 9.8

One 3.2-kg paint bucket is hanging by a cord from another 3.2-kg paint bucket, also hanging by a cord, as shown in the figure (Figure 1). The cords accelerating the buckets, each has a weight of 2.1 N. Part A If the two buckets are pulled upward with an acceleration of 1.10m/s^2 by the upper cord, determine the tension in each cord at three points of attachment. Express your answer using two significant figures. Tin lowest point = 27 N Part B Express your answer using two significant figures. Tin middle point = _____________ N Part C Express your answer using two significant figures. Tin highest point = __________ N

Explanation / Answer

When the buckets are pulled upwards with an acceleration ... there is a resultant force acting upwards

For the lower bucket:

ma = T - mg

T = m(a + g)

T = 3.2(1.1+ 9.8)

T = 34.88 N vertically up


) For the higher chord the tension will be double what it is for the lower cord ... b/c a and g are the same but the mass is doubled

so for the higher chord T = 2 x 34.88 = 69.76 N vertically up
