Centripetal acceleration:

$\overline{){\mathbf{a}}{\mathbf{=}}\frac{{\mathbf{v}}^{\mathbf{2}}}{\mathbf{r}}}$, where v is the speed and r is the radius of the circular path.

Initially,

$\begin{array}{rcl}{\mathbf{a}}_{\mathbf{1}}& \mathbf{=}& \frac{{\mathbf{\left(}\mathbf{2}\mathbf{v}\mathbf{\right)}}^{\mathbf{2}}}{\mathbf{R}}\end{array}$

An object traveling at speed 2V in a circle of radius R has an acceleration a. If both speed and radius are doubled, the new acceleration will be?

Multiple choice answers:

a. 3a

b. 2a

c. 4a

d. a
