Question

Formula One racers speed up much more quickly than normal passenger vehicles, and they also can stop in a much shorter distance. A Formula One racer travelling at 90 m/s can stop in a distance of 110 m.

Answer 1

Answer

given,

initial speed of the car = 90 m/s

final speed of the car = 0 m/s

distance taken to stop = 110 m

calculating the acceleration of the car = ?

using the equation of motion

v² - u² = 2 a s

0² - 90² = 2 x a x 100

$a = \dfrac{-90^2}{2\times 100}$

   a = 40.5 m/s²

acceleration of the formula one car is equal to a = 40.5 m/s²
