Answer:
1200kg
Step-by-step explanation:
In order to solve this, we need to know the following formula...
F = ma (where F is the force, m is the mass, and a is the acceleration)
Now we change the formula to our needs and get...
![m = (F)/(a)](https://img.qammunity.org/2022/formulas/physics/high-school/1729ljae7ascaes90qehdd7nuq09xzrxe9.png)
Now plug in the values and get...
![m = (F)/(a) = (1800)/(1.5) = 1200 kg](https://img.qammunity.org/2022/formulas/physics/middle-school/3z206o3fer15h3yz3m2bewapf8bd5sv9p1.png)
