An unsuspecting bird is coasting along in an easterly direction at 1.00 mph when a strong wind from the south imparts a constant acceleration of 0.200 m/s^2 . If the wind's acceleration lasts for 2.20 s , find the magnitude and direction (measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. Assume that the bird is originally travelling in the + direction and that there are 1609 m in 1 mi .
