what is the weight in newtons of a 250-g package of breakfast cereal?
m g = .25 g = .25 * 9.81
on earth approximately
2.45N
To find the weight of a package in newtons, we need to first convert the mass of the package from grams to kilograms.
1. Start by converting grams to kilograms. There are 1000 grams in a kilogram, so we divide the mass in grams by 1000.
250 grams ÷ 1000 = 0.25 kilograms
2. Next, use the formula for weight, which states that weight equals mass multiplied by the acceleration due to gravity. The acceleration due to gravity on Earth is approximately 9.8 m/s^2.
Weight = Mass × Acceleration due to gravity
Weight = 0.25 kilograms × 9.8 m/s^2
3. Finally, multiply the mass in kilograms by the acceleration due to gravity to find the weight in newtons.
Weight = 0.25 kilograms × 9.8 m/s^2
Weight ≈ 2.45 newtons
Therefore, the weight of the 250-gram package of breakfast cereal is approximately 2.45 newtons.
