Thanks! You are right, of course. I have it down with "y"s rather than x, and that 0.19m as a y instead. . I did 2mgho - (ky^2)/2 - mgy Solving for y: y=0.23meters I'm not sure if I messed up the symbols though... should I be adding the final potential forces instead of subtracting (because we...

ho + 0.19m, however, I set the top of the spring as y=0, so those extra 0.19m do not have to be included in the gravitational potential energy, right? I don't see why there'd be kinetic energy in the system when the spring is compressed- the block is not moving and the spring has potential...

Homework Statement A 700g block is released from rest at height Ho(initial) above a vertical spring with spring constant k=400 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 19.0 cm. How much work is done A) by the block on the spring...
