Solving a Constant Acceleration Problem: Help from Phil

[truetaurus]

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?

thanks
phil

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

ya i know that, but I am stuck where i can start from?

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.
