The Magnitude of a Particle’s Vector

Part 1

A particle has a trajectory given as \(\vec{r} = (\) \(5t^2 + 6t\) \() \hat{\imath} + (\) \(9t^2 + 6t\) \() \hat{\jmath}\) \(m\) for \(t\) given in seconds. What is the magnitude of the velocity vector for this particle at \(t = \) \(20\) \(s\)?

Answer Section
