Homework Help: Motion in 2D

    An object moves clockwise with decreasing speed around an oval track. THe velocity vectors are in the top right side of the oval labeled G and H respectively. They lie fairly close to one another. I have a few questions:

    IF point H were chosen to lie closer to point G, describe how the change in velocity vector would change (direction and magnitude)?
    I am thinking that the direction would stay the same but the magnitude would decrease because the time intervals are smaller.

    Describe how you determine the acceleration at point G (direction and mag)?
    I have no idea!
