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

Point P rotates around the center O at a constant rate.The magnitude of the velocity of point P relative to O is 3.7 m/s and the distance between the two points is 90 mm. What are the magnitudes of (a) normal and (b) tangential components of the acceleration of P relative to O?

2. Relevant equations

a_{n}= v^{2}/r

3. The attempt at a solution

So I was able to find the normal component of acceleration using the formula a_{n}= v^{2}/r and got value of 152.11 m/s/s. But for tangential component, I'm confused, the point doesn't actually accelerate (it travels at a constant speed). So does that mean that a_{t}would equal to zero? Or am I misunderstanding something here?

Thank you!
