To find the distance traveled by the car during the 10-second interval, you can use the equation of motion:
distance = average velocity × time
Since the car's velocity is changing uniformly from 20 m/s to 40 m/s, we can find the average velocity by taking the average of the initial and final velocities.
average velocity = (initial velocity + final velocity) / 2
Plugging in the values:
average velocity = (20 m/s + 40 m/s) / 2 = 30 m/s
Now we can calculate the distance:
distance = average velocity × time = 30 m/s × 10 s = 300 meters
Therefore, the car traveled a distance of 300 meters during the 10-second interval.
