23 A smart car weighs 4000 N . What is its mass in kg (with units)?

To find the mass of the smart car in kg, we can use the formula: \[ \text{Mass} = \frac{\text{Weight}}{g} \] where: - Mass is the mass of the object in kg (kg), - Weight is the weight of the object in Newtons (N), - \( g \) is the acceleration due to gravity, which is approximately 9.81 m/s². Given that the weight of the smart car is 4000 N, we can substitute the values into the formula to find the mass in kg. Calculate the value by following steps: - step0: Calculate: \(\frac{4000}{9.81}\) - step1: Convert the expressions: \(\frac{4000}{\frac{981}{100}}\) - step2: Multiply by the reciprocal: \(4000\times \frac{100}{981}\) - step3: Multiply: \(\frac{4000\times 100}{981}\) - step4: Multiply: \(\frac{400000}{981}\) The mass of the smart car is approximately 407.75 kg.
