Question

1. what happens to the required space as a vehicles speed increases?

□ it decreases
□ it stays the same
□ it increases
□ it disappears

Explanation:

To determine what happens to the required space (like stopping distance) as a vehicle’s speed increases, we use the physics concept of motion. The stopping distance (a type of required space for safety) is related to speed by the formula \( d=\frac{v^{2}}{2a} \) (where \( v \) is speed, \( a \) is deceleration). As speed (\( v \)) increases, the stopping distance (\( d \)) increases because it is proportional to the square of speed. So the required space (e.g., stopping space) increases with speed.

Answer:

It increases
