A car is travelling with linear velocity ' V ' on a circular road of radius 'r'. If its velocity is increasing at a rate of ' a ' ms^-2, then the resultant acceleration will be

Question

Accepted Answer

Correct answer: B. (b) Radial acceleration, a_r= V^2r Tangential acceleration, a_t=a Resultant acceleration, a_R= a_r^2+a_t^2 = ( v^2r )^2+a^2= v^4r^2+a^2
