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

41 k

Step-by-step explanation:

Use the formula for weight: W = m × g. Rearrange the formula to solve for m:

m = W ÷ g.

Substitute W = 400 newtons and g = 9.8 N/kg into the formula. Then divide:

m = 400 N ÷ 9.8 N/kg

40.8 kg.

Rounded to the nearest kilogram, Lincoln has a mass of 41 kilograms.

Answer 2

Weight equals mass times gravitational acceleration=400N, so mass=400/9.8=41kg approx.
