Formula One racers speed up much more quickly than normal passenger vehicles, and they also can stop in a much shorter distance.
Afina-wow [57]

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

vazorg [7]

Answer:

a) 3.00×10⁸ m/s

b) 2.9979×10⁸ m/s

c) 2.997925×10⁸ m/s

Explanation:

299792458 m/s is the speed of light

Let us write this in scientific notation first

2.99792458×10⁸ m/s

a) In three significant figures

We need to round the number to the hundredths place

3.00×10⁸ m/s

b) In five significant figures

We need to round the number to the ten thousandths place

2.9979×10⁸ m/s

c) In seven significant figures

We need to round the number to the millionths place

2.997925×10⁸ m/s
