When driving your car at speed v through a turn of radius r, the centripetal acceleration is a1. What will be the acceleration, if you drive at the same speed through a turn of half the radius?Explanation / Answer
a1 = v^2 /r
if halves the speed.
acc. = (v/2)^2 / r = a1 /4
acc. get 1/4 th times.
a1 =v^2 / r
if half the radius , acc. will get doubled.
if twice the speed, acc. will get 4 times.
