During a physics experiment, a student uses a motion sensor to record the position of a small toy car moving along a straight track. The car starts from rest, accelerates uniformly for 5 seconds, then continues at a constant speed for another 15 seconds before it comes to a stop. The total distance covered by the car is 120 meters. Based on this information, calculate the speed of the car after the first 5 seconds of motion.

The speed of the car after the first 5 seconds of motion is approximately 9.47 meters per second.

The speed of the car after the first 5 seconds of motion is approximately 7.12 meters per second.

The speed of the car after the first 5 seconds of motion is approximately 6.85 meters per second.

The speed of the car after the first 5 seconds of motion is approximately 7.74 meters per second.

The speed of the car after the first 5 seconds of motion is approximately 8.62 meters per second.
