Question

I dont even know where to start, please show work please!

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 0.400 m/s f the acceleration from the wind lasts for 3.80 s, fin the magnitude, r, and direction, 6, of the bird's displacement during this time period. HINT: assume the bird is originally travelling in the +x direction and there are 1609 m in 1 mile.) Number 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 35.0 degree angle to the original direction of motion. If the magnituc of the acceleration is 0.500 m/s2, find the displacement vector r, and the angle of the displacement, 01. Enter the components of the vector and angle below. (Assume the time interval is still 3.80 s.) Number Number m Number

Explanation / Answer

initial speed in m/s=0.44704 meters / second
so,the displacement in x direction=vot
=1.6986m
displacement in y direction=1/2at^2
=2.888m
so,

=arctan(2.888/1.6986)

=59.54degrees above the x axis

magnitude=(1.6986^2+2.888^2)^1/2

=3.35 m
