Classic advice gives an estimation of 53.34m. How wet the conditions are, how worn your tyres are, what type of surface youre travelling on, how tired you are.. Too many factors to give a definiteive answer, but the UK highway code says 53m for a car on dry, firm surface with an alert driver. Be advised that these are the stopping distances for a 1970 Ford anglia with drum brakes. The stopping power of a modern car is far better; my Volvo S60 will emergency stop from 50mph in less than 20 metres, but this excludes thinking time, which can vary hugely depending on the driver
175 feet. The Oregon Drivers Handbook calculates it at closer to 240 feet. (of course many factors can make it more or less distance.)
The typical BREAKING distance from 50mph is 38meters, but the overall stopping distance is 53meters (overall stopping distance is made up of thinking distance, which is 15meters in this case, + breaking distance)
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
120ft.I discovered a formula for calculating it for any given speed. I've tested it for 20mph, 30mph,40mph,50mph,60mph and 70mph. The formula is as follows:overall stopping distance in ft = Sp x (1 + Sp/20).Where Sp is the magnitude of the speed in mph.So at 40mph it is:40 x (1 + 40/20) = 50 x (1 + 2) = 40 x 3 = 120ft.
The speed is still 50mph, no matter the distance measured...
50 Mph X 3.5 = 175 feet = 53.3 metressee http://www.hintsandthings.co.uk/garage/stopmph.htm for explanation and various equations
8 hours at 50mph the whole time no stopping or getting slower or getting faster.
45-50mph and can maintain this speed for a long distance.
200 miles
Distance is a scalar quantity, it is only a measurement. Whereas displacement is a vector quantity, it is both a measurement and a direction. Speed is scalar, velocity is vector. Speed=50mph, Velocity=50mph to the north. Pretty simple concept once you know the difference.
50mph = 80.47kmh
time= distance/rate =318miles / 50mph =6.36 hours
