Final answer:
The weight of the car is 7840 N.
Step-by-step explanation:
To calculate the weight of the car, we can use Newton's second law of motion, which states that force exerted on an object is equal to its mass multiplied by its acceleration. In this case, the force applied by Mariusz Pudzianowski is 2400 N with an acceleration of 3 m/s^2. We can rearrange the formula to solve for the mass of the car:
Force = Mass × Acceleration
2400 N = Mass × 3 m/s^2
Mass = 2400 N ÷ 3 m/s^2 = 800 kg
Therefore, the weight of the car is equal to its mass multiplied by the acceleration due to gravity, which is approximately 9.8 m/s^2. The weight of the car is:
Weight = Mass × Acceleration due to gravity
Weight = 800 kg × 9.8 m/s^2 = 7840 N
