Question

is considered circular with a diameter of 2b. A participant starts his vehicle manages to increases his speed at a constant rate of α. Obtain a simplified expression between his velocity and his acceleration as a function of time

Answer 1

We know that circuler path particle move

Then two force are work

$F_{ext}=\frac{mv^2}{b}$

$F{ext}=m\alpha$

$m\alpha=\frac{mv^2}{b}$

$\alpha=\frac{v^2}{b}$

Where b radius of circuler path
