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...
