The pair of blocks shown is released from rest when the springs are unstretched. The coefficients of static and kinetic friction are 0.25 and 0.15, respectively. For ensuing motion, find: a) maximum speed of the blocks and the stretch in the springs at that position, b) maximum distance the 10kg block slides down the incline, c) will the blocks rebound from the position of part B. Each spring has a stiffness of 0.25 KN/m.
