A driver with a perception-reaction time of 2.5s is driving with a speed of 75 kmph. He observes an accident on the road ahead. Workout the distance the vehicle will travel before the driver applies brakes.

A driver with a perception-reaction time of 2.5s is driving with a speed of 75 kmph. He observes an accident on the road ahead. Workout the distance the vehicle will travel before the driver applies brakes. Correct Answer 52 m

d = 0.278 S.t here, d = reaction distance S = initial speed of vehicle, kmph t = reaction time, s = 2.5 seconds d = 0.278 X S X 2.5 d = 0.278 X S X 2.5 d = 52.125 m = 52 m (approx.)

The first working steam­ powered vehicle was designed and most likely built by Ferdinand Verbies, a Flemish member of a Jesuit mission in China around 1672. It was a 65 cm long scale­ model toy for the Chinese Emperor, that was unable to carry a driver or a passenger. It is not known if Verbiest's model was ever built. Nicolas- Joseph Cugnot is widely credited with building the first full­ scale, self ­propelled mechanical vehicle or automobile in about 1769; he also created a steam­ powered tricycle. He constructed two steam tractors for the French Army, one of which is preserved in the French National Conservatory of Arts and Crafts. His inventions were however handicapped by problems of water supply and maintaining steam pressure. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam ­powered road vehicle. It was unable to maintain sufficient steam pressure for long periods. Sentiment against steam ­powered road vehicles led to the Locomotive Acts of 1865. In 1807 Nicephore Niepce and his brother Claude probably created the world's first internal combustion engine which they called Pyreolophore.
