An individual is running around a turn with an 11-m radius at 3.75 m/s. What is the runner's centripetal (radial) acceleration?

Well
1. transform to angular velocity
w=(3.75/11)=0.34.... because (w=velocity/radious)
For definition of centripetal acceleration is like:
a=r*w^2
replacing we have
a=(11)*(0.34)^2=1.27m/s^2
