Now, assume the same bird is moving along again at 3.00 mph in an easterly direction, but this time, the acceleration given by If the magnitude of the acceleration is \( 0.500 \mathrm{~m} / \mathrm{s}^{2} \), find the displacement vector \( \vec{r} \) and the angle of the displacement \( \theta_{1} \).
Enter the displacement components \( r_{x} \) and \( r_{y} \) and the angle \( \theta_{1} \). Assume the time interval is still 3.10 s .
