Question

Use the approximation that 

vavg = pf/m

 for each time step.

A spring with a relaxed length of 25 cm and a stiffness of 13 N/m stands vertically on a table. A block of mass 79 g is attached to the top of the spring. You pull the block upward, stretching the spring until its length is now 28.4 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. (Assume the +y direction is upward. Express your answers in vector form.)
