Homework Statement
An ideal spring of an un-stretched length 0.10 m is placed horizontally on a frictionless table. One end of the spring is fixed and the other end is attached to block of mass M = 10 kg. The 10 kg block is also attached to a massless string that passes over a small frictionless pulley. A block of mass m = 2 kg hangs from the other end of the string. When this spring-and-blocks system is in equilibrium, the length of the spring is .20 m.
Calculate tension in the string.
Calculate the force constant of the spring.
(there is a diagram, but it is complicated and I don't know how i would get it on here)
