Answer:
2.08 kg
Step-by-step explanation:
Newton's second law states that the acceleration of an object is proportional to the force applied to the object, according to the equation:

where F is the force applied, m is the mass of the object and a its acceleration.
In this situation, the soccer ball is kicked with a force F=13.5 N and its acceleration is a=6.5 m/s^2, therefore its mass is
