Yes, -2 does not satisfy the other two equations.The 1st equation in which you solved for t also has the result of t=-2. Will this change anything?

\(\displaystyle -2\) is not in the domain of \(\displaystyle \vec{r}\), because \(\displaystyle \log(t+1)-\exp(t)\) would not exist for \(\displaystyle t=-2\).The 1st equation in which you solved for t also has the result of t=-2. Will this change anything?

does that mean that the answer is correct?\(\displaystyle -2\) is not in the domain of \(\displaystyle \vec{r}\), because \(\displaystyle \log(t+1)-\exp(t)\) would not exist for \(\displaystyle t=-2\).

Yes! As far as I can follow your workings.does that mean that the answer is correct?

It should be \(\displaystyle \vec{v}(0)+t~\vec{v}~'(0)\)
