Two blocks each have a mass 1.7 kg and are attached to links that are pin-connected to bar BC as shown. The masses of the links and bar are negligible, and the blocks can slide without friction. Block D is attached to a spring of constant k = 720 N/m. Knowing that block A is at rest when it is struck horizontally with a mallet and given an initial velocity of 250 mm/s, determine the magnitude of the maximum displacement of block D during the resulting motion. 450 mm mm. 600 mm k -^^^^^^ The magnitude of the maximum displacement of block Dis 15.496
