There a five positions (A=-10cm, B=-5cm, C=0cm, D=5cm, E=5cm). A block is at rest at location C when a student pulls it to position A. The student then releases the block and it begins to oscillate. Given the block has a mass of 2kg and the spring has a constant of 40 N/m, what is the block's maximum magnitude of acceleration and at what location(s) does it occur?
D and E seem to be the same position. Please verify the wording of your question
