Suppose that a block is dropped from rest onto a spring that is oriented vertically. The block falls 1.5 m before landing on the spring (spring constant = 160 N/m) and compressing it 12 m before the block and spring momentarily come to rest. (The spring then pushes the block upward.) What is the mass of the block? Use g= 10 m/s^2. A. 0.66 B. 1 C. 2 D. 8 E. none of these is within 3% of the correct answer.
