$15 A car can accelerate at 5.6 m/s². Starting from rest, how long will it take to reach a speed of 24.0 m/s?

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.
