Answer:
833 kg
Step-by-step explanation:
The problem can be solved by using Newton's second law:
![F=ma](https://img.qammunity.org/2020/formulas/physics/middle-school/hoqv0uuwk5hamoxytydy5e8slsjemaiqzz.png)
where
F is the net force acting on the object
m is the mass of the object
a is the acceleration
Here we know:
F = 1250 N
![a=1.5 m/s^2](https://img.qammunity.org/2020/formulas/physics/middle-school/pq4usz4j5h7dxt3xzykxeyk13egzktb8of.png)
Therefore, we can solve the formula for m to find the mass of the object:
![m=(F)/(a)=(1250)/(1.5)=833 kg](https://img.qammunity.org/2020/formulas/physics/middle-school/f9ag4i9p6q4apmcg6sb1iua5bdolyfn5ct.png)
