which factor can influence braking distance?
a speed
b radius
c length
d temperature

Explanation:

Braking distance is the distance a vehicle travels from the moment the brakes are applied until it comes to a complete stop. The formula for braking distance \(d = \frac{v^{2}}{2a}\) (where \(v\) is the initial speed and \(a\) is the deceleration). Radius, length, and temperature (in a non - extreme, normal operating range for vehicle components) do not directly affect the braking distance formula in the way speed does. Speed \(v\) is squared in the formula, so an increase in speed has a significant impact on braking distance.

Answer:

A. speed
