Calculate Average Velocity of a Truck

Click For Summary
SUMMARY

The discussion focuses on calculating the average velocity of a truck that travels at two different speeds: 80 m/s and 40 m/s over a distance of 1200 meters. The correct formula for average velocity is derived from the total displacement divided by the total time taken. Participants highlight the need for additional information regarding the duration of travel at 80 m/s to accurately compute the average velocity, as the initial attempts using the formula ave V = (u + v)/t were unsuccessful.

PREREQUISITES
  • Understanding of average velocity calculations
  • Familiarity with the formula for average velocity: ave V = change in distance / time
  • Basic knowledge of kinematics
  • Ability to manipulate equations to solve for unknown variables
NEXT STEPS
  • Research the kinematic equations for motion with constant acceleration
  • Learn how to calculate total time from speed and distance
  • Explore examples of average velocity calculations in physics
  • Study the implications of varying speeds on average velocity
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding motion and velocity calculations.

1 A truck travels along a staright road at 80 m/s and it travels at 40 m/s for the next 1200m. what is the average velocity?


2. ave V= change d/ time
r=dt (get the total time)




3. (1600-1200)/ 50
this is incorrect

I also tried ave V= (u+v)/t and it did not work

Is that all of the information you have been given? Were you not told how long the truck is moving at 80 m/s for?
