SUMMARY

The discussion focuses on calculating the velocity of a particle experiencing constant acceleration. The particle has an initial velocity of 43.4 m/s east and a constant southward acceleration of 2.3 m/s². After 7.6 seconds, the resultant velocity is determined to be 60.8 m/s. To find the direction of this velocity, participants suggest using the tangent of the angle derived from the ratio of the southward and eastward components.

PREREQUISITES
  • Understanding of kinematic equations for motion in two dimensions
  • Knowledge of vector components and their calculations
  • Familiarity with trigonometric functions, specifically tangent
  • Basic principles of acceleration and velocity
NEXT STEPS
  • Study kinematic equations for two-dimensional motion
  • Learn how to resolve vectors into components
  • Explore trigonometric functions and their applications in physics
  • Practice problems involving constant acceleration in a plane
USEFUL FOR

Students and professionals in physics, particularly those studying mechanics, as well as educators looking for practical examples of motion in a plane.

A particle experiences a constant acceleration that is south at 2.3 m/s2. At t = 0, its velocity is 43.4 m/s east. What is its velocity at t = 7.6 s?

I got 60.8 m/s but it also asks for the direction in degrees and I'm not sure how to find that.

Dividing the y by the x will give you the tangent of the angle

(and remember that the angle increases anticlockwise! :wink:)
