Relevant Equations

displacement = x
force of spring -> mass (M) = F = -kx

A mass (M) is attached to a spring (K). Mass moves in a one dimensional plane (horizontally)
1) If mass M is initially at x=0, what is the minimum Work required to bring it to x=x0 ? PE ?
2) M is released from x=x0, PE when x=xo/2 ? KE ?
3) PE when x=0 ? KE ?
4) PE when x=-x0/2 ? KE ?
5) What is the largest negative x value will become ? PE ? KE ?

velocity is not nessesary to find for 2,3,4
