Average Average velocity Velocity

Click For Summary

SUMMARY

The average velocity during a trip can be calculated using the formula for uniform acceleration, which states that the average velocity equals one-half the sum of the initial velocity (Vo) and the final velocity (Vf). In the given scenario, if a car travels at 100 km/h for one hour and then comes to an instantaneous stop, the average velocity is determined by the equation 1/2(Vo + Vf). Therefore, with Vo at 100 km/h and Vf at 0 km/h, the average velocity is 50 km/h.

That's actually the formula for uniform acceleration.

Let's say I drive my car for an hour at 100km/h, then I crash into a wall and instantaneously come to a halt. What was my average velocity during the trip? What is 1/2(Vo+Vf)?
