1. A block of mass 1.5 kg is attached to the end of a vertical spring of force constant k=300 N/m. After the block comes to rest, it is pulled down a distance of 2.0 cm and released. (a) What is the frequency of the resulting oscillations? (b) What are the maximum and minimum amounts of stretch of the spring during the oscillations of the block? (a) 2.3 Hz (b) 2.9 cm and 6.9 cm I used the formula T = 2(pie)(squaroot of m/k) with f = 1 /T and found the first answer; however, I'm now sure how to calculate the answers for the second part of the question. F = k*x (spring constant times displacement, but I'm not sure how that factors in to the two answers. Thanks in advance.
