Answer:
s = 67.5 m/s
Explanation:
Skid mark for the car = 190 ft
given equation of speed and distnace
[tex]s = \sqrt{24d}[/tex]
d is the distance
s is the speed Â
[tex]s = \sqrt{24\times 190}[/tex]
[tex]s = \sqrt{4560}[/tex]
[tex]s =67.52 m/s[/tex]
rounding off the answer to the nearest tenth
s = 67.5 m/s
The speed of the car before it stop is equal to s = 67.5 m/s
