Changning velocity, check please

    changing velocity, check please

    The arrows indicate the velocity.

    This is the object's motion in three equal time frames.


    The arrow that shows the direction of the change in velocity would have to be: <--


    What if the velocity was constant and the object went from 0----> to pointing south-west in the next time frame? Then the magnitude of the arrow that shows the direction of the change in velocity would be down correct?

    First part seems ok.

    Initially, the object is pointing east in the second problem. If the object were to then point south-west in the next time frame, there would have to be something that causes it to change from east to west. Thus it would not point directly downwards, but at an angle towards the west side of south.

    Sorry, bad wording, I mean south east

    Oh, then yeah, you're right.
