Final answer:
The net applied force responsible for the acceleration of the scooter is 9.5 N.
Step-by-step explanation:
To determine the net applied force responsible for the acceleration, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = ma). In this case, the mass of the scooter is 3.8 kg and the acceleration is 2.5 m/s². Therefore, the net applied force can be calculated as:
F = ma = (3.8 kg)(2.5 m/s²) = 9.5 N
Thus, the net applied force responsible for the acceleration is 9.5 N.
