One 2.6-kg paint bucket is hanging by a massless cord from another 2.6-kg paint bucket, also hanging by a massless cord. Required:
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 1.50 m/s2 by the upper cord, calculate the tension in each cord.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
