**QUESTION=**

a bird takes 8.5 s to fly from position A to position B along the path. determine the bird's average acceleration.

va= 4.4 m/s (3 degrees S of E) -- is this the initial velocity?

vb= 7.8 m/s ( 25 degrees N of E) -- is this the final velocity?

THIS IS WHAT I GOT SO FAR, I"M NOT SURE IF IT IS RIGHT AT ALL -->

ay = vfy - vfi / time

i found , ax = 0.52

ay = 0.92

a(2) = ax(2) + ay(2)

= (0.52)2 + (0.92)2

= 0.29 + 0.85

= √1.14 m/s(2)

therefore, average acceleration = 1.07 m/s

tan = 0.92 \ 0.52

tan = 60.4 degrees

Therefore the average acceleration of the car is 1.07 m/s (60.4 degreesN of E)
