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 0.200 m/s2. if the acceleration from the wind lasts for 2.70 s, find the magnitude, r, and direction, θ, 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.) a) 3.59 m, and 8.59º
b) 3.59 m, and 17.2º
c) 4.88 m and 8.59º
d) 4.88 m and 17.2º

The correct answer is option 'c'.

Explanation:

Since for motion along orthogonal axis are independent thus we conclude that the motion of the bird is unchanged along the easterly direction.

Speed in easterly direction is 4.00 mph which is converted to meters per second as

Thus the distance covered in x-direction for 2.7 seconds equals

Now in for the motion in southern direction is uniformly accelerated thus the distance covered in 2.7 seconds can be evaluated using second equation of kinematics as

This the displacement is given by

The angle is given by

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
