(B) The car experiences two types of acceleration while moving on a circular path with increasing speed:$1$. Radial (centripetal) acceleration: $a_r = \frac{V^2}{r}$, which is directed towards the center of the circular path.$2$. Tangential acceleration: $a_t = a$, which is directed along the tangent to the path.Since these two accelerations are perpendicular to each other, the resultant acceleration $a_R$ is given by the vector sum:$a_R = \sqrt{a_r^2 + a_t^2}$Substituting the values:$a_R = \sqrt{(\frac{V^2}{r})^2 + a^2}$$a_R = \sqrt{\frac{V^4}{r^2} + a^2}$
