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 0.500 m/s². If the wind's acceleration lasts for 2.50 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 = = Now, assume the same bird is moving along again at 1.00 mph in an easterly direction, but this time, the acceleration given by the wind is at a o = 30.0° angle to the original direction of motion, measured counterclockwise from the easterly direction. If the magnitude of the acceleration is 0.600 m/s², find the displacement vector 7 and the angle of the displacement 01. Enter the comnonents of the vector, r. and r.. and the angle. Assume the time interval is still 2.50 s.
