Use the approximation that 3mg = 3f/m for each time step. A spring with a relaxed length of 25 cm and a stiffness of 16 N/m stands vertically on a table. A block of mass 74 g is attached to the top of the spring. You pull the block upward, stretchingthe spring until its length is now 29.0 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 ofthe block at a time 0.2 s after you release the block. (Assume the + y direction is upward. Express your answers in vector form.)
