Calculate Bird's Average Acceleration

Click For Summary
SUMMARY

The discussion focuses on calculating a bird's average acceleration while flying from position A to position B over a time span of 8.5 seconds. The initial velocity (Va) is 4.4 m/s at an angle of 31 degrees South of East, and the final velocity (Vb) is 7.8 m/s at an angle of 25 degrees North of East. Participants emphasize the importance of using vector diagrams to accurately determine the change in velocity, which is essential for calculating average acceleration using the formula: average acceleration = (Vb - Va) / time.

PREREQUISITES
  • Understanding of vector addition and subtraction

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
