Change your resolution using the slider. Clicking the Resolution drop-down menu in Windows 7 and 8 will display the slider. Drag the slider to change the display resolution on your monitor. Resolutions other than the recommended one will result in a blurry, stretched, or squished image. Selecting a lower resolution will increase the size of objects on your screen.
You should reduce your speed by 1/3 on wet roads and by 1/2 or more on snow packed roads. If you would normally be traveling at a speed of 60 mph on dry pavement, then on a wet road. you should reduce your speed to 40 mph, and on a snow-packed road you should reduce your. speed to 30 mph. When you come upon slick, icy roads you should drive slowly and cautiously.
A tripling of the speed would increase the stopping distance by a factor of nine. And a quadrupling of the speed would increase the stopping distance by a factor of 16. The stopping distance is proportional to the square of the speed of the vehicle.This mathematical relationship between initial speed and stopping distance is depicted in the animation below. Three cars with identical braking systems are traveling three different speeds..5*m*v 2 = F*d. The above equation shows that the stopping distance (d) is proportional to the square of the speed (v 2). And that's exactly what the driver's education course taught you. And now you know: it's PHYSICS ! For more information on physical descriptions of motion, visit The Physics Classroom Tutorial.
