I believe this represents Newton's first law of motion. Any object in motion will continue to move until a force stops it, be it friction or a physical object.
Answer:
Mass = 1350kg
Explanation:
Given the following data;
Velocity = 23m/s
Momentum = 31,050 kg·m/s.
To find the mass of car;
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
Substituting into the equation, we have
31,050 = mass*23
Mass = 31,050/23
Mass = 1350kg
Therefore, the mass of the car is 1350 kilograms.
