my question is still how does the acceleration factor into this problem? I'm trying to work the problem out and I'm not getting the question right I don't understand what I am doing wrong. am I using the right formula?

oh yea, sorry but the acceleration should be included?

Why is the acceleration part of the kinematic equation? And if there is a range (0-3.055) then what number should I insert? Otherwise was the way I was going about solving it right? Thanks

Homework Statement A toy car of mass 555g is moving with speed 1.21m/s and strikes a spring mounted to the wall. The spring slows the toy car to rest with a acceleration that varies from 0 - 3.055m/s2. Determine the spring constant. Homework Equations W = -1/2mv2 + 1/2 kx2 The Attempt at a...
