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 traveling at 90 m/s can stop in a distance of 110 m. What is the magnitude of the car's acceleration as it slows during braking?

Respuesta :

Answer:

a = -36.8 m/s/s

Explanation:

Initial speed of the car

[tex]v_i = 90 m/s[/tex]

finally car will stop after it cover the distance

[tex]d = 110 m[/tex]

so we have

[tex]v_f^2 - v_i^2 = 2 a d[/tex]

here we have

[tex]0 - 90^2 = 2(a) (110)[/tex]

[tex]a = \frac{90^2}{220}[/tex]

[tex]a = -36.8 m/s^2[/tex]
