# If v=5x, find x when t=2 ? ( x=displacement, t= time in seconds) watch

1. Is it possible to find x when t=2, given that v=5x?
There were other informations but i didn't find anything else relevant, is the v=5x enough information to solve it?
2. v = dx/dt...
3. (Original post by DFranklin)
v = dx/dt...
v=\int 5x dt
I thought of that.
Then what to do?

Nope, (speed = difference in distance divided by difference in time), and conversely ... so your equation is equivalent to . If you flip both sides you get , which you can then integrate and rearrange to find the value of .

Oh that simple. Thanks.
