A delivery robot experiences acceleration a→(t)=4i^+(2t)j^\(\overrightarrow{a}\)\(\left\)(t\(\right\))=4\(\hat{i}\)+\(\left\)(2t\(\right\))\(\hat{j}\) from t=0t = 0 to t=3 st=3\(\text{ s}\). What is the magnitude of its change in velocity over that interval?

A delivery robot experiences acceleration $\vec{a} (t) = 4 \hat{i} + (2 t) \hat{j}$ from $t equals 0$ to $t equals 3 s$ . What is the magnitude of its change in velocity over that interval?
