How does the braking distance of the vehicle change dependent on the speed increase?
aThe braking distance increases with an increase in speed.
bThe braking distance is decreses with an increase in speed.
cThe driving speed has no influence on the braking distance.
Why?
Under the same conditions, a higher speed means a longer braking distance because more of the vehicle's kinetic energy must be dissipated. The wheel shown transfers braking force to the road through the tyre, which has limited grip. Increasing speed therefore neither shortens the braking distance nor leaves it unchanged.
