Q. A 220 g block hangs from a spring with spring constant 12 N/m. At t=0;{rm s} the block is 31cm below the equilibrium point and moving upward with a speed of 89.0 cm/s. What is the block's distance from equilibrium while the speed is 30 cm/s?
Q. The 2-kg collar C is free to slide along the smooth shaft AB. Determine the acceleration of collar C if (i) the shaft is fixed from moving and (ii) collar A is subjected to an acceleration of 2 m/s2 to the left. In all cases, the motion occurs in the vertical plane.
