A block weighing 22 N oscillates at one end of a vertical springfor which k = 130 N/m; the other end of the spring is attached to aceiling. At a certain instant the spring is stretched 0.23 m beyondits relaxed length (the length when no object is attached) and theblock has zero velocity. (a) What is the net force on the block atthis instant? What are the (b) amplitude and (c) period of theresulting simple harmonic motion? (d) What is the maximum kineticenergy of the block as it oscillates?
