Asked by Mellanie

A car starts a race from rest on a circular track and has a tangential speed of 43 m/s at the end of the third lap. The track has a radius of 91 m. If it has constant angular acceleration, what is the magnitude of its tangential acceleration?

Help me and please explain in simple terms because I'm very confused.

a(τ) =ε•R =(v²/2•φ) •R =v²•R/2 • 2•π•N = v²•R/4•π•N
