?The position vector for a particle is \(\mathbf{r}(t)=t \mathbf{i}+t^{2}
Chapter 3, Problem 82(choose chapter or problem)
The position vector for a particle is \(\mathbf{r}(t)=t \mathbf{i}+t^{2} \mathbf{j}+t^{3} \mathbf{k}\). The graph is shown here:
Find the acceleration at time t = 2 sec.
Text Transcription:
r(t) = t i + t^2 j + t^3 k
