McCluskey's goal was a stunning individual effort as he got the ball some 35 yards metres out and skirted past 35-year-old McManus before running another 10 yards to lash to the roof of the net despite Rory Beggan's best efforts. The last line in Equation 4 gives us the acceleration of the car. We call the distance moved . You at the zero-end, me with the spool of tape, recording length, reporting metres, centimetres back to base, then leaving up the stairs, the line still feeding out, unreeling years between us. The normal force is mg because it only has to counter the weight of the car. The car decelerates (accelerating in the opposite direction of its motion) because there is an unbalanced force on it.

The driver has to make a decision - go through the yellow light or stop at the white line separating the intersection. Thinking distance is the distance travelled in the time that it takes you, as the driver, to realise you must brake in order to avoid a hazard directly ahead of you. Small increases in speed result in bigger increases in stopping distances. Read about our approach to external linking. For example 20mph x 2 = 40 feet 30mph x 2.5 = 75 feet 40mph x 3 = 120 feet 50mph x 3.5 = 175 feet 60mph x 4 = 240 feet 70mph x 4.5 = 315 feet There are 3.3 feet in a metre - so divide the distance in feet by 3.3 to get the stopping distance in metres. It is the shortest distance in the stopping distance equation because a driver's reaction time is so small. The thinking distances given in the government's estimate of stopping distances are based on a reaction time of 0.67 seconds, There are many different variants that determine the stopping distance of your vehicle including size of car, speed, weather and the driver's attention levels. You come to help me measure windows, pelmets, doors, the acres of the walls, the prairies of the floors.
