Integrating with another variable help!!
Is it possible to integrate -(1/2)vdt, with respect to t?

Re: Integrating with another variable help!!
You're not going to integrate $-(1/2)vdt$ wrt to $t.$

The equation that you have is solved by separation of variables.

Rewrite it as $\frac{dv}{v}=-\frac{1}{2}dt,$ and integrate the lhs wrt $v$, the rhs wrt $t.$
