No. Negative acceleration means that you are decreasing in acceleration, like braking a car. Therefore, you can't be speeding up because speed and acceleration are connected. You can't travel at a faster speed if you are braking.
10 meters for thinking distance and 17 meters for stopping
Most certainly for without friction the braking system would fail no matter how much force was applied.
Stopping distance as in braking distance: Braking distance refers to the distance a vehicle will travel from the point where the brakes are fully applied to when it comes to a complete stop. It is affected by the original speed of the vehicle, the type of brake system in use, the reaction time of the driver/rider and the cefficient of friction between the tires and the road surface.
yes
True
Yes, the faster you are moving the longer it will take to stop.
Braking means stopping. Accelerating means speeding up. Think about it.No.He is decelerating.
Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop.
On dry, level pavement, with decent tires? About 120 feet. Many things affect this calculation. With worn tires the distance can increase to 210 feet. Dirt roads require longer braking distances than pavement. Ice can increase the braking distance by hundreds of feet. Braking down a hill, depending upon the slope, can double the braking distance, whereas braking up hill can halve that distance. If you lock the tires, you typically increase the braking distance. You can reduce the distance by pumping the brakes. Anti-lock brakes allow the tires to slip, which decreases the braking distance. Extra weight in the vehicle increases the braking distance. Refer to the link below for calculating the braking distance at different speeds with different tire wear on dry, level pavement.
Braking distance
Braking in a moving vehicle is applying the brakes to slow or halt movement, usually by depressing a pedal. The braking distance is the distance between the time the brakes are applied and the time the vehicle comes to a complete stop.
in rain, snow or ice your tires have much less traction, and therefore need more braking distance.
