[SOLVED] acceleration and velocity 1. The problem statement, all variables and given/known data EXACT PROBLEM: A car accelerates from rest W at 5.0m/s2 for 10.0s, then continues this acceleration NE for another 10.0s. What is the average velocity of the car for its journey to its position after 20.0s? 2. Relevant equations average velocity=average displacement/time Delta x=Vit + 1/2at^2 Vf=Vi+at 3. The attempt at a solution First, I found Delta x and Vf for the west vector than found Delta x for the NE vector. Then I tried to find the displacement using Pythagoreans theorem but it was not the correct answer.
