Homework Statement
A 700 g block is released from rest at height h0 above a vertical spring with spring constant k = 380 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 24.0 cm.
(a) How much work is done by the block on the spring?
(b) How much work is done by the spring on the block?
(c) What is the value of h0?
(d) If the block were released from height 2.00h0 above the spring, what would be the maximum compression of the spring?
Homework Equations
(KEi + PEi) + W = (KEf + PEf)
W = F*d cos (thet)
F=kx
The Attempt at a Solution
I plugged in .24m*380N/m (x * k) for the force the spring exerts, but I'm not quite sure what to do from here to get teh work for part a. any help is greatly appreciated, even just getting me started.
