A 1200 kilogram automobile moving at 30 m/s slows down and comes to a stop after 95 m. Albert Einstein came up with the equation E = mc2, which states that when a body's energy changes by an amount E, its mass (m) changes by an amount equal to E/c2.
A 1200 kilogram automobile moving at 30 m/s slows down and comes to a stop after 95 m.The Braking Acceleration is calculated using the equation shown below.
[tex]Ab = V^2 / (2*SD)Ab = V^2 / (2*SD)Ab = 150^2 / (2*10)=1125 (m/s^2)[/tex]
This equation states that the stopping distance is inversely related to the square of the vehicle's speed at the moment the brakes are applied. In other words, d u2.d=ku2 where the proportionality constant k is dependent on the units used.
The distance a vehicle travels between when its brakes are fully applied and when it comes to a complete stop is known as the braking distance or stopping distance. Measured on dry pavement, this distance is frequently provided as a 100-0kph distance, for example, 56.2m.
