Question

3. Two systems (a) and (b) are released from rest from the initial position x(0) = 0.4 m and the first 1.2 seconds of their response is recorded. In system (a), the blocks are connected by a rigid rod of mass m' = 0.6 kg. In system (b), the blocks always remain in contact during motion of the lower block. (25 points) a) Briefly explain which plot shows the response of each system. b) Determine the values of m, k, and ??k. c) If ?s = 0.15, determine after how many half-cycles each system eventually comes to rest.
