Finding average/final velocity and acceleration.

Click For Summary
SUMMARY

The discussion focuses on calculating average velocity, final velocity, and acceleration for an object moving with constant acceleration. The initial velocity is given as 10.0 m/s [S], and the object travels 720 m in 45 seconds. Key kinematic equations used include average velocity as the total displacement divided by total time and the relationship between initial and final velocities. The participant successfully distinguishes between average and final velocity after clarification.

PREREQUISITES
  • Understanding of kinematic equations
  • Knowledge of average and final velocity concepts
  • Familiarity with constant acceleration motion
  • Basic algebra for solving equations
NEXT STEPS
  • Study the derivation and application of the five kinematic equations
  • Learn how to calculate acceleration using the formula Vf = Vi + at
  • Explore real-world applications of average and final velocity in physics
  • Practice problems involving constant acceleration scenarios
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone seeking to understand motion under constant acceleration.

Homework Statement


An object with an initial velocity of 10.0m/s moves 720m in 45s along a straight line iwht constant acceleration. For the 45s interval, find its average velocity, final velocity and acceleration.

Homework Equations


5 Kinematic equations:
d=1/2(Vf+Vi)t
Vf=Vi+at
d=Vit+1/2at^2
d=Vft-1/2at^2
Vf^2=Vi^2+2ad

I can't seem to distinguish between the final and average velocity. The acceleration part is simple enough. Thanks :)

average velocity = total displacement divided by total time

(which, for constant acceleration, = (vi + vf)/2)
 
Thanks, I got the answer.
