Use the approximation that 7')an = 3} fm for each time step. A spring with a relaxed length of 25 cm and a stiffness of 11 Nr'm stands vertically on a table.A block of mass 73 gis attached to the top of the spring.You pull the block upward, stretching the spring until its length is now 31.3 cm, hold the block at rest for a moment, and then release it. Using a time step of 0.1 s, predict the position and momentum of the block at a time 0.2 s after you release the block. (Assu me the +3; direction is upward. Express your answers in vector form.)I Part 1 ta}? =
