(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A car initially traveling due north goes around a semicircle having a radius of 500 m at a constant speed of 20 m/s. A) How long does this take? B) What is the magnitiude and direction of the average acceleration?

2. Relevant equations

a = Δv_{x}/Δt(xhat)+Δv_{y}/Δt(yhat)

3. The attempt at a solution

I'm stumped as to how to start this problem. I drew out a half circle with the radius showing 500 m for the distance. I'm not sure if I'm missing a formula or what as I didn't see anything relevant for circles on my formula sheet from my class. Any help is appreciated.
