So this is the question;
Road accidents involving children could be reduced by reducing the speed limit outside a school to 20 mph. Discuss the effect this would have on the road safety near a school where the speed limit is currently 30 mph.
AND this is the answer I put;
If the car, travelling at 30 mph were to hit a child, the force would e much greater as the acceleration would be greater as -u^2/2s would be -11.25m^-2. Also taking into account the thinking distance and breaking distance, the thinking distance would be twice the velocity but braking distance is squared the velocity, therefore taking longer to stop.
Now i'm too sure about this answer that I have given,and think i'm missing a few points so if there's any fault in it or any extra info I can add please don't hesitate
