An unsuspecting bird is coasting along in an easterly direction at 4.00 mph when a strong wind from the south imparts a constant acceleration of 0.300 m/s². If the wind's acceleration lasts for 3.40 s, find the magnitude r and direction 0 (measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. Assume that the bird is originally travelling in the +x direction and that there are 1609 m in 1 mi. r =
