Answer:
Speed = 24 m/s.
No! It doesn't break the speed limit.
Explanation:
The formula we'll be using to find the car's speed:
[tex] \boxed{ \mathsf{speed = \frac{distance}{time} }}[/tex]
The detectors are placed 1.2 m apart.
==> Distance the car travels = 1.2 m
The car, it says, takes 0.050 s to travel that distance.
==> Time taken by the car to travel 1.2 m = 0.050 s
Using the formula mentioned above, let's calculate the speed of the car:
[tex] \sf{speed = \frac{distance}{time} }[/tex]
[tex] \implies \sf{speed = \frac{1.2}{0.050} }[/tex]
On dividing 12 by 0.050 we obtain 24.
[tex] \implies \sf{speed = 24 \: m/s }[/tex]
Any car traveling with a speed that is greater than or equal to 25 m/s is breaking the speed limit.
And since the car in our focus is traveling at 24 m/s that is less than 25 m/s, it doesn't break the speed limit.
