Homework Statement
Find the velocity x' as a function of the displacement x for a particle of mass m, which starts from rest at x =0, subject to the following force function:
F0 + cx
Homework Equations
Fx = m d2x/dt2
ax=Fx/m=x''=v dv/dx
The Attempt at a Solution
So I'm pretty sure I'm doing this wrong, perhaps not, but the question confused me. Right now I've rearranged the equation so it looks like
x''dx=vdv
and when I integrate both sides it becomes:
v2/2 = F0x+cx2/2
And then I multiply the right side by two and square root? It seems wrong to me. Any help would be much obliged.
