Homework Help: What is the direction of the acceleration ?

  1. Sep 23, 2007 #1
    1. The problem statement, all variables and given/known data

    The direction of an object's velocity changes uniformly from east to north. What is the direction of the acceleration ?

    2. Relevant equations

    3. The attempt at a solution

    would the acceleration be North East ?

    Same direction of the velocity -.-

    That's a rather ambiguous question. Let's assume it's a car going around a bend in the road. Then, at any given moment, the direction of the acceleration is opposite to the way all the passengers are lurching, i.e., sideways towards the inside of the bend. That direction starts off being North as you enter the bend, then it's North West at the middle of the bend, then it's West just as you leave the bend. So what they expect for a one-word answer is a mystery to me. If they want the average of the acceleration over that time period, it's North West. I'd flunk the examiner though.
