Can you please help me with part 1 of this question.My answers are wrong.thank you so much for your time

Use the approximation that U avg = p /m for each time step. A spring with a relaxed length of 25 cm and a stiffness of 20 N/m stands vertically on a table. A block of mass 66 g is attached to the top of the spring. You pull the block upward, stretching the spring until its length is now 29.4 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.) Part 1 Your answer is partially correct. ( a) r = m Save for Later Attempts: 9 of 10 used Submit Answer Part 2 Your answer is correct. ( b ) p =
