Mechanics 2 Help

Could anyone please help me with this question, I just really don't understand it at all :frown:

A model aircraft is flying at 10m/s in a horizontal circle of radius 15m. Draw a vector triangle to find the change in velocity in the interval in which its velocity changes direction from 000* to 030* and hence find the average acceleration. In what direction would you expect its acceleration to be in at the instant when it is flying in the direction 000*.

Any help much appreciated, thanks :smile:

Have you drawn out the circle and triangle? It might be best to have initial velocity as 10 j (North vector) and have an expression for the 030 velocity in terms of i (East vector) and j too.
