The position vector locates a particle as a function of
Chapter , Problem 10(choose chapter or problem)
The position vector \(\vec{r}=5.00 t \hat{i}+\left(e t+f t^{2}\right) \hat{j}\) locates a particle as a function of time t. Vector \(\vec{r}\) is in meters, t is in seconds, and factors e and f are constants. Figure 4-31 gives the angle \(\theta\) of the particle’s direction of travel as a function of t (\(\theta\) is measured from the positive x direction). What are
(a) e and
(b) f, including units?
