Homework Help: Circular Motion

  1. Oct 11, 2007 #1
    I got the following question:

    When the car reaches point A it has a speed of 4 m/s, which is increasing at a constant rate of 2 m/s2. Determine the time required to reach point B and the magnitudes of its velocity and acceleration.

    See attachment for how the diagram looks like.

    Now i am not sure how to go about solving this? I have worked out the arc of the half circle but now what?

    concepts involved in this problem:
    uniform circular motion
    tangential acceleration and velocity
    centripetal acceleration due to uniform circular motion

    perhaps the next step is to identify potentially relevant equations and see if they give you a hint as to how to relate the concepts.
