6 Not complete Points out of 2.00 A spring that has a block firmly attached to it on one end is stretched a length delta x. At some point the block is released. What is its speed (in m/s) as it passes through the equilibrium position of the spring (xo) if the mass of the block is 3.73 kg. Assume that the points xo and X are 11.58 cm and 21.3 cm away from the wall respectively, and the force constant of the spring is 501 N/m. The block moves without friction
