Abird starts from the ground, flies at a certain speed for 5 seconds, and lands on a tree branch. the vector representing its position is . it continues to fly in the same direction and at the same speed for 5 more seconds, and lands on another branch. what vector represents its new position from the ground?

Answer with explanation:

Let the Speed at which bird is flying = u m/s

⇒Distance = Speed × Time

So,After 5 Seconds , position of Bird = 5 u meter

After,10 Seconds , position of Bird = 10 u meter

If ground is considered as two dimensional plane,and time is represented on X axis(i plane) and Distance on Y axis(j plane),,then

Position of bird after 5 seconds= (5, 5 u)=5 i + 5 u jFirst Branch

Position of bird after 10 seconds= (10, 10 u)=10  i+10 u jSecond Branch(New Position)

Change in position of bird =Final Position - Initial Position

                      =1 0  i + 10 u j - 5 i -5 u j  

                     = 5 i +5 u  j

b). 4320 have a nice day

hi i’m going tomorrow morning and i can come over and you out with this stuff for me haha ya day is going crazy and i’ll tell you what i’m talking about you don’t wanna go do you think i’m going to be a good friend i just don’t know how much you mean about the stuff you want to do and stuff you know i just want you and you know that i’m going crazy i don’t think i’m going crazy about going tomorrow and i’ll tell ya hey i don’t think i’m going crazy about going tomorrow and i’ll tell you what i’m done
