Homework Statement
A cyclist is initially heading exactly due North. He then initiates a turn to the West, the turn being a quarter circle with radius 12-m. He travels at a constant speed of 5.5-m/s during the turn. What is the direction of this average acceleration, measured anti-clockwise from East?

0.25*2*12*Pi/12=1.57
This value seems way too small. Am I suppose to apply tan inverse to it which gives me 57 degrees?
