From the given information:
- Taking the movement of the Duck in the North as the x-direction
- The movement of the Duck in the East direction as the y-direction
However, we will have to compute the initial velocity and the acceleration of the duck in their vector forms.
<h3>In vector form;</h3>The initial velocity is:
The acceleration is:
The objective of this question is to determine the speed of the duck at a certain time. Since it is not given, let's assume we are to determine the Duck speed after 4 seconds of accelerating;
Then, it implies that time (t) = 4 seconds.
Using the first equation of motion:
Then, we can replace their values into the equation of motion in order to determine the speed:
Collect like terms:
Thus, the magnitude is:
Therefore, we can conclude that the speed of the duck after 4 seconds is 1.34 m/s
