Average acceleration of a car changing speed and direction

Click For Summary
SUMMARY

The discussion focuses on calculating the average acceleration of a car that is changing speed and direction. The key method involves performing vector subtraction on the two given velocity vectors to obtain the resultant vector. This resultant vector is then divided by the time interval of 8 seconds to determine the average acceleration. This approach is essential for accurately analyzing motion in physics.

PREREQUISITES
  • Understanding of vector subtraction in physics
  • Familiarity with velocity vectors
  • Basic knowledge of acceleration concepts
  • Ability to perform calculations involving time intervals
NEXT STEPS
  • Research vector subtraction techniques in physics
  • Learn about calculating average acceleration in different contexts
  • Explore the implications of changing speed and direction on motion
  • Study the relationship between velocity, acceleration, and time
USEFUL FOR

Physics students, automotive engineers, and anyone interested in understanding motion dynamics and acceleration calculations.

Homework Statement
A car, travelling initially at 28 m/s [W25 ̊N], takes 8 s to change its velocity to 25 m/s [S]. What is the average acceleration over this time interval?
Relevant Equations
a = vf-vi / t
Nevermind I found what I had to do, thank you though.

You basically have to do one vector subtraction (subtract the 2 given vectors of velocity and keep the result as vector) and then 1 division by 8sec.
