(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

find velocity x dot, as function of time t, for particle mass m starts x=0, t=0

subject to force where Fo and c are constants.

Fx = Fo + ct

2. Relevant equations

answer is

x dot =Fo/m t + c/2m t^2

3. The attempt at a solution

obviously it is just an integration.

but how does the "m" get in there.

i know this is a simple question, but the solution eludes me

i have stuff like

Fo=c=constant

F=ma

F=mv dot = m r dotdot

d=r=vt=dv/dt

x dotdot = dv/dt = F/m = a = constant

what is Fx - is the the force component in direction x , or is it a vector , ?

what is Fo - a constant, vector?

how do you add in a t

how about

Fx dt = Fo dt + ct dt

Fo = ma = m v dot

x dot = int Fo dt + int ct dt

= int dt + 1/2 c t^2

=

... and im lost
