Calculate Bird's Average Acceleration

[quickslant]

A bird takes 8.5s to fly from position A to Position B along a path (looks like a parabolic curve facing downward) determine the birds average acceleration

Va = 4.4 m/s [31 S of E]
Vb = 7.8 m/s [25 N of E]

I would draw a vector diagram to find the acceleration.

va + change in v = vb

The change in v plus the time given allows you to calculate the aceleration
