Answer:
Mass, m = 1561.23kg
Explanation:
Given the following data;
Weight = 15300N
We know that acceleration due to gravity is equal to 9.8m/s²
To find mass;
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;

Where;
- m represents the mass of an object measured in kilograms.
- g is the acceleration due to gravity measured in meters per seconds square.
Substituting into the equation, we have;

<em>Mass, m = 1561.23 Kg</em>
<em>Therefore, the mass of the car is 1561.23 kilograms.</em>
