What work is done by the spring?

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

- Physics - please help me.. -
**Elena**, Tuesday, December 31, 2013 at 12:49pmW(block) =kx²/2=252•0.29²/2=10.6 J

W(spring) = - 10.6 J

mv²/2 = kx²/2

v=x•sqrt(m/k)=

=0.29•sqrt(0.395/252) =0.0115 m/s
