Problem 13.030.b - Determine work of a spring Determine the maximum velocity achieved by the block. The maximum velocity achieved by the block is [ m/s. Required information Problem 13.030 - Determine work of a spring NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 15-kg block is attached to spring A and connected to spring B by a cord and pulley. The block is held in the position shown with both springs unstretched when the support is removed and the block is released with no initial velocity. The constant of each spring is 2 kN/m. B A k = 2 kN/m M C www k = 2 kN/m Problem 13.030.a - Determine work of a spring Determine the velocity of the block after it has moved down 50 mm. The velocity of the block after it has moved down 50 mm is m/s.
