Use the approximation that 7 avg = I?) f lmfor each time step. A block is attached to the top of a spring that stands vertically on a table. The spring stiffness is 51 N/m, its relaxed length is 38 cm, and the mass of the block is 315 g. The block is oscillating up and down as the spring stretches and compresses. At a particular time you observe that the velocity of the block is m/s and the position of the block is m relative to an origin at the base of the spring. Using a time step of 0.1 s, determine the position of the block 0.2 5 later
