Answer:
The net applied force responsible for the acceleration is 15.3 N.
Explanation:
According to Newton's second law of motion, the net unbalanced force acting on any object is directly proportional to the product of mass and acceleration acting on that object. So
[tex]Force = Mass *Acceleration[/tex]
As the mass of the object is given as 5.1 kg and the acceleration attained by the object or scooter is 3 [tex]m/s^{2}[/tex], then the net applied force on the scooter is
[tex]Net applied force = 5.1 kg * 3 m/s^{2} =15.3 N[/tex].
Thus, the net applied force responsible for the acceleration is 15.3 N.
