Question

How much stopping distance will we get if we double the initial speed of the vehicle?​

Answer 1

We know from third equation of motion that s(distance) is directly proportional to u^2. Thus, if the speed is doubled then then the stopping distance becomes 4 times the given value

Answer 2

Answer:

Braking distance is the time it takes for your car to come to a complete stop after you've hit your brakes. When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four.
