Answer:
m = 2.01[kg]
Step-by-step explanation:
This problem can be solved using Newton's second law which tells us that the force applied on a body is equal to the product of mass by acceleration.
![F =m*a](https://img.qammunity.org/2021/formulas/physics/high-school/1e5663dcqiruxbyd6b0555s7v12ozt6ula.png)
where:
F = force = 12.5 [N]
m = mass [kg]
a = acceleration = 6.2 [m/s²]
![12.5=m*6.2\\m = 2.01[kg]](https://img.qammunity.org/2021/formulas/physics/high-school/rlhtpspr1jdeishl6r6lfzb9l7y4v9kxjj.png)
