Vehicle Velocity#
A truck’s position as a function of time is given by \(\vec{r} =\) (\(t^2 -\) \(t)\hat{\imath} + (\) \(t^{-1}+\) \(t^3)\hat{\jmath}\) where \(\vec{r}\) is in meters and \(t\) is in seconds.
Part 1#
What is the truck’s velocity at \(t=\) 2 \(s\)?
Answer Section#
(10\(\hat{\imath}\) + 34\(\hat{\jmath}\)) \(m/s\)
(10\(\hat{\imath}\) + 36\(\hat{\jmath}\)) \(m/s\)
(8\(\hat{\imath}\) + 28\(\hat{\jmath}\)) \(m/s\)
(8\(\hat{\imath}\) + 34\(\hat{\jmath}\)) \(m/s\)
(10\(\hat{\imath}\) + 28\(\hat{\jmath}\)) \(m/s\)
