3. [-/2 Points] DETAILS SERCP11 13.2.OP.008. MY NOTES A 2.60 kg block rests upon a frictionless, horizontal surface. The block is attached to a horizontal spring (of force constant - 485 N/m) whose other end is anchored to a nearby wall. The block is pulled until it lies a distance x, 5.25 cm from its equilibrium position (x-0). The block is then released and undergoes simple harmonic motion. (a) Calculate how much work must be done (in 3) to stretch the spring from equilibrium (0) to the pre-release position () (b) with what speed (in m/s) does the block pass through the equilibrium position once it has been released from x m/s Need Help?
