What work is done by the spring?

What was the speed of the block just before it hit the spring?

- Physics - please help!! -
**bobpursley**, Monday, December 30, 2013 at 8:45amThe energy in the spring at stopping has to be be equal to the KE when hitting the springl.

1/2 k (.29^2)=1/2 mass*V^2=work done by spring
