APFIVE Average Acceleration from Velocity Vector
A particle moves in a plane with velocity $$\vec{v} = (3t^2 \hat{i} + 4t^3 \hat{j})$$ m/s, where $$t$$ is in seconds. What is the magnitude of the average acceleration vector between $$t = 1$$ s and $$t = 2$$ s?
A
9$$\sqrt{13}$$ m/s²
B
13 m/s²
C
$$\sqrt{865}$$ m/s²
D
5$$\sqrt{13}$$ m/s²
