Velocity of a Vector Valued Function

Question

The position of a particle is given by the vector function $$\mathbf{r}(t)= \langle 2t+1, t^2 \rangle$$. What is the velocity vector of the particle at $$t=1$$?

Accepted Answer

The velocity vector at $$t=1$$ is $$\langle 2,2 \rangle$$.

Answer

The velocity vector at $$t=1$$ is $$\langle 3,2 \rangle$$.

Answer

The velocity vector at $$t=1$$ is $$\langle 1,2 \rangle$$.

Answer

The velocity vector at $$t=1$$ is $$\langle 2,1 \rangle$$.
