Question

One 2.5 kg paint bucket is hanging by a massless cord from another 2.5 kg paint bucket, also hanging by a massless cord, as shown in Fig. 4-44.

(a) If the buckets are at rest, what is the tension in each cord?
(lower cord)________ N
(upper cord)________ N

(b) If the two buckets are pulled upward with an acceleration of 1.70 m/s2 by the upper cord, calculate the tension in each cord.
(lower cord)________ N
(upper cord)_________N

Answer 1

a.)1st-> 2.5*2 = 5kg
5kg(9.8m/s^2) = 49N
2nd-> 2.5kg(9.8m/s^2)= 24.5N

b.)1st-> 5kg(9.8m/s^2 - 1.70m/s^2)
= 5kg(8.1m/s^2)
= 40.5N
2nd-> 2.5kg(8.1m/s^2)
= 20.25N
