I'm sorry to bother anyone but this question is really driving me insane. It's one of my question on my notes and I've been trying to re-solve it.

It's in oscillatory unit and apparently we have to know what the speed is.

A 4.00kg mass is an horizontal frictionless surface attached to a spring with k=20.0N/m. The mass is pulled 0.300m from a equilibrium, then let go.

2. Relevant equations

max speed

3. The attempt at a solutionThe answer is suppose to be 0.671m/s but I keep getting 0.612m/s...

..Never mind I figured it out.
