Ответ:To find the time it takes for the car to reach a speed of 24.0 m/s, we can use the formula:
t = v / a,
where t is the time it takes for the car to reach the desired speed, in seconds;
v is the final velocity, in meters per second;
a is the acceleration, in meters per second squared.
Plugging in the values given, we get:
t = 24.0 m/s / 5.6 m/s² = 4.3 s.
So it will take the car approximately 4.3 seconds to reach a speed of 24.0 m/s starting from rest.
