One 3.2kg paint bucket(B) is hanging by a massless cord from another 3.2kg paint bucket(A), also hanging by a massless cord.
a.) if the buckets are at rest, what is the tension in each cord?
b.) if the two buckets are pulled upward with an acceleration of 1.6m/s2 by the upper cord, calculate the tension in each cord.
this is one of the problems im confused with actually
all i can make out is :
1. finding the tension when at rest
box[a] ==> FtensA = (agrav)(mA) + Ftens B
box ==> FtensB = (agrav)(mB)
2. finding the tension force given the acceleration 1.6m/s2
box[a]==>FtensA = mAaA +FtensB
box==>FtensB = mBaB
The Attempt at a Solution
I tried to solve for the tension when at rest and this is how it turned out:
FtensA = (9.8m/s2)(3.2kg) + FtensB
= 31.6N + 31.6N
FtensB = (9.8m/s2)(3.2kg)
Then I tried to solve for the tension given the acceleration
FtensA = (1.6m/s2)(3.2) + FtensB
= 5.12N + 5.12N
FtensB = (1.6m/s2)(3.2kg)
I really think that I'm wrong in here because its really confusing...
Thanks In Advance! :)
