Question

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 0.300 m/s2. If the wind's acceleration lasts for 3.20 s, find the magnitude r and direction e (measured counterclockwise from the easterly direction) of the bird's displacement over this time interval. (HINT: assume the bird is originally travelling in the +x direction and there are 1609 m in 1 mile.) Number m Number 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 38.0 degree angle to the original direction of motion. If the magnitude of the acceleration is 0.500 m/s2, find the displacement vector r, and the angle of the displacement, 8 Enter the components of the vector and angle below. (Assume the time interval is still 3.20 s.) Number Number m Number
