Answer:
The radius of the curve that Car 2 travels on is 380 meters.
Explanation:
Speed of car 1,
Radius of the circular arc,
Car 2 has twice the speed of Car 1,
We need to find the radius of the curve that Car 2 travels on have to be in order for both cars to have the same centripetal acceleration. We know that the centripetal acceleration is given by :
According to given condition,
On solving we get :
So, the radius of the curve that Car 2 travels on is 380 meters. Hence, this is the required solution.
