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

Your answer is partially correct. Use the approximation that U avg = P y /m for each time step. A block is attached to the top of a spring that stands vertically on a table. The spring stiffness is 55 N/m, its relaxed length is 30 cm, and the mass of the block is 330 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 s later. T = 0 0.9 > m
