To find the time it will take for the car to stop, we can use the equation:
v = u + at
Where:
v = final velocity (0 m/s because the car stops)
u = initial velocity (24 m/s)
a = acceleration (-8.0 m/s^2)
t = time
Rearranging the equation to solve for t:
0 = 24 + (-8)t
-24 = -8t
t = 3 s
Therefore, it will take 3 seconds for the car to come to a stop. The answer is 3 s.
