A 10-kg block is attached to spring A and connected to spring B by a cord andpulley. The block is held in the position shown with both springs unstretched whenthe support is removed and the block is released with no initial velocity. Knowing thatthe constant of each spring is 2 kN/m, determine (a) the velocity of the block after ithas moved down 50 mm, (b) the maximum velocity achieved by the block
