Answer:
It will take 33 seconds to stop the car.
Explanation:
Using the first equation of kinematics we have
[tex]v=u+at[/tex]
where
'v' is final speed of object
'u' is initial speed of object
'a' is acceleration of object
't' is time of acceleration of object
Now since it is given that [tex]a=-2km/s^{2}[/tex] since acceleration is negative and [tex]u=66km/s[/tex]
We know that the object will stop when it's velocity reduces to zero hence in the equation above setting v = 0 we get
[tex]0=66-2\times t\\\\\therefore t=\frac{66}{2}=33seconds[/tex]
