Determine the weight in newtons of a car whose mass is 1400 kg. Convert the mass of the car to slugs and then determine its weight in pounds.<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

To find the weight of a car with a mass of 1400 kg, we need to determine the weight in two units: Newtons (N)<\/strong> and pounds (lbs)<\/strong>. The weight of an object depends on its mass and the gravitational force acting on it.<\/p>\n\n\n\n

Step 1: Convert the Mass to Weight in Newtons (N)<\/h3>\n\n\n\n

The weight of an object is given by the formula:<\/p>\n\n\n\n

[
W = m \\cdot g
]<\/p>\n\n\n\n

Where:<\/p>\n\n\n\n

    \n
  • (W) is the weight in newtons.<\/li>\n\n\n\n
  • (m) is the mass of the object.<\/li>\n\n\n\n
  • (g) is the acceleration due to gravity, which on Earth is approximately 9.81 m\/s\u00b2.<\/li>\n<\/ul>\n\n\n\n

    Given:<\/p>\n\n\n\n

      \n
    • Mass of the car, (m = 1400 \\, \\text{kg})<\/li>\n\n\n\n
    • Gravitational acceleration, (g = 9.81 \\, \\text{m\/s}^2)<\/li>\n<\/ul>\n\n\n\n

      Substituting the values:<\/p>\n\n\n\n

      [
      W = 1400 \\, \\text{kg} \\times 9.81 \\, \\text{m\/s}^2 = 13734 \\, \\text{N}
      ]<\/p>\n\n\n\n

      Thus, the weight of the car in newtons is 13734 N<\/strong>.<\/p>\n\n\n\n

      Step 2: Convert the Mass to Slugs<\/h3>\n\n\n\n

      In the imperial system, mass is often measured in slugs<\/strong>. To convert from kilograms to slugs, we use the following conversion factor:<\/p>\n\n\n\n

      [
      1 \\, \\text{kg} = 0.0685218 \\, \\text{slugs}
      ]<\/p>\n\n\n\n

      So, for a car with a mass of 1400 kg:<\/p>\n\n\n\n

      [
      \\text{Mass in slugs} = 1400 \\, \\text{kg} \\times 0.0685218 \\, \\text{slugs\/kg} = 95.93 \\, \\text{slugs}
      ]<\/p>\n\n\n\n

      Thus, the car’s mass is approximately 95.93 slugs<\/strong>.<\/p>\n\n\n\n

      Step 3: Determine the Weight in Pounds<\/h3>\n\n\n\n

      In the imperial system, weight is typically measured in pounds (lbs)<\/strong>, and weight in pounds is related to mass in slugs by the equation:<\/p>\n\n\n\n

      [
      W_{\\text{lbs}} = m_{\\text{slugs}} \\times 32.174 \\, \\text{ft\/s}^2
      ]<\/p>\n\n\n\n

      Where 32.174 ft\/s\u00b2 is the gravitational acceleration in the imperial system.<\/p>\n\n\n\n

      Substituting the values:<\/p>\n\n\n\n

      [
      W_{\\text{lbs}} = 95.93 \\, \\text{slugs} \\times 32.174 \\, \\text{ft\/s}^2 = 3080.63 \\, \\text{lbs}
      ]<\/p>\n\n\n\n

      Thus, the weight of the car is approximately 3080.63 pounds<\/strong>.<\/p>\n\n\n\n

      Final Answers:<\/h3>\n\n\n\n
        \n
      • Weight in Newtons<\/strong>: 13734 N<\/li>\n\n\n\n
      • Mass in Slugs<\/strong>: 95.93 slugs<\/li>\n\n\n\n
      • Weight in Pounds<\/strong>: 3080.63 lbs<\/li>\n<\/ul>\n\n\n\n

        I’ll now generate an image to summarize this.<\/p>\n\n\n\n
