Question

The stopping distance of a moving vehicle is proportional to the (A) initial velocity (B) cube of the initial velocity (C) square of the initial velocity (D) cube root of the initial velocity

When brakes are applied to a moving vehicle, the distance is travels before stopping is called stopping distance. It is given by s=(u2/2 a), where u is initial velocity and a is the retardation produced by brakes.

Q. The stopping distance of a moving vehicle is proportional to the

initial velocity

cube of the initial velocity

square of the initial velocity

cube root of the initial velocity

square root of the initial velocity

When brakes are applied to a moving vehicle, the distance is travels before stopping is called stopping distance. It is given by $s = \frac{u ^{2}}{2 a}$ , where $u$ is initial velocity and $a$ is the retardation produced by brakes.
