Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I got a ball in a circualar motion on a frictionless table and in a uniform circle.

I need to calculate the tangential acceleration and radial acceleration.

What I know:

Radius: 0.4m

Tangential velocity: 0.50m/s^-1 (constant)

Are theese formulas right for this problem?

Radial acceleration = V^2 / r

Tangential acceleration = r*angular acceleration

Because I am confused when I mix tangential velocity with radial acceleration and so on.. and I need some help on how I can calculate the angula acceleration for the tangential acceleration.

Every bit of information would help alot!

Thanks
