Homework Help: Finding the position at a change in direction

  1. Feb 10, 2010 #1
    1. The problem statement, all variables and given/known data

    A particle moving along a straight line with constant acceleration starts its motion at t = 0. The particle is observed to change the direction of motion at t = 4 s, and when t = 10 s it reaches the position of −2 m with a −2.4 m/s velocity measured from a chosen reference frame. Find the position of the particle when it changes its direction of motion.
    Ans: 5.2 m
