Question

Lincoln weighs 400 newtons. What’s his mass rounded to the nearest kilogram? Assume that acceleration due to gravity is 9.8 N/kg.

Answer 1

Answer: 41!

Step-by-step explanation:

Answer 2

m = 40.8 [kg]

Step-by-step explanation:

We know that weight is defined as the product of mass by gravitational acceleration in this way we have the following equation.

`W = m*g`

where:

W = weight [N] (units of Newtons)

m = mass [kg]

g = gravity acceleration = 9.8 [N/kg]

Therefore:

`m=W/g\\m=400/9.8\\m=40.8[kg]`
