One 3kg paint bucket is hanging by a massless cord from another 3kg pain bucket, also hanging by a massless cord.
a) If the buckets are at rest, what is the tension in each cord?
b) If the buckets are pulled upward with an acceleration of 2.6 m/s^2 by the upper cord, calculate the tension in each cord.
a) Mg (lower cord); 2 Mg (upper cord)
b) M*(g+a) (loer cord);
2M(g+a) (upper cord)
Do the numbers. Answers will be in Newtons if you use the right value for g, in m/s^2.
