The overall stopping distance would be around 122m (400ft) This is made up of a thinking distance of 24m (79ft) and an actual stopping distance of 98m (321ft). The thinking distance is around 3m for every 10mph of speed and the overall stopping distance is calculated as follows: 2x20 ft at 20mph 2.5x30 ft at 30mph 3x40 ft at 40mph 3.5x50 ft at 50mph 4x60 ft at 60mph 4.5x70 at 70mph 5x80 at 80mph = 400 ft james s
10 meters for thinking distance and 17 meters for stopping
using the formula, speed squared divided by 20 plus speed gives 40 feet approximate stopping distance at 20mph.
You can use a ratio here, say 40mph/150ft = 80mph/xft then cross multiply: 40x = 150 * 80 40x = 12000 x = 300
(80mph / 60minutes)*2minutes= 2.666 miles
Speed = Distance/Time ex.: Distance - 50mi. Time - 2.5 hours 50mi. / 2.5hours = 20mph Speed - 20mph
Speeding in Arizona is a criminal offense for any speed 20mph over a posted speed limit or any speed over 80mph.
8:08am when train b reaches the station the distance from train a is 12 miles. the relative speed between the trains is 20mph passing 12 miles in 20mph takes 0.6 hours which is 36 minutes. 36 minutes after 7:32 is 8:08
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
