After the block comes to rest, it is pulled down a distance of 27 m and released. with .5 kq cars (a) Determine the force constant of the spring CHatches, it if ann (b) What is the unloaded length of the spring? Pulled Down (c) What is the frequency and period of the resulting oscillations? (d) What are the minimum and maximum amounts of stretch of the spring durin the oscillations of the block
