What is the weight in newtons of a 250 g package of cereal?
need answer and work shown asap! plz and thank u!
"The newton is the unit of force derived in the SI system; it is equal to the amount of force required to accelerate a mass of one kilogram at a rate of one metre per second per second."
from http://en.wikipedia.org/wiki/Newton
So a mass of 1 kilogram has a weight of 1*g=9.81 newtons, where g is the acceleration due to gravity in m/s²
How much is the weight exerted by a mass of 250 g?
To find the weight in newtons, you first need to convert the mass of the package from grams to kilograms.
Step 1: Convert the mass from grams to kilograms:
Given that the mass of the package is 250 grams, you need to divide it by 1000 to convert it to kilograms:
250 grams / 1000 = 0.25 kilograms
Step 2: Calculate the weight in newtons:
The weight in newtons can be calculated using the formula W = m * g, where W represents the weight, m represents the mass, and g represents the acceleration due to gravity.
In this case, the acceleration due to gravity is approximately 9.8 m/s^2.
Therefore, the weight can be calculated as follows:
Weight = Mass * acceleration due to gravity
Weight = 0.25 kg * 9.8 m/s^2
Weight ≈ 2.45 newtons
So, the weight of the 250 g package of cereal is approximately 2.45 newtons.
