This is a beautiful problem to test whether a student actually understands
Newton's 2nd law of motion . . . Force = (mass) x (acceleration).
That simple law is all you need to solve this problem, but you need to
use it a few times.
m₁ alone:
Force = (mass) x (acceleration)
36 N = ( m₁ ) x (6 m/s²)
m₁ = (36 N) / (6 m/s²)
m₁ = 6 kilograms .
m₁ and m₂ glued together:
Force = (mass) x (acceleration)
36 N = (6 kg + m₂) x (2 m/s²)
6 kg + m₂ = (36 N) / (2 m/s²) = 18 kilograms
m₂ = 12 kilograms .
m₂ alone:
Force = (mass) x (acceleration)
36 N = (12 kg) x (acceleration)
Acceleration = (36 N) / (12 kg)
Acceleration = 3 m/s²
Answer:
a
Explanation:
the answer is a because it is feasible
<span>Det är behållaren med lock.</span>
The answer is Real Numbers. The Real Number best describes the displayed weights on a digital scale that shows each weight to the nearest half pound. Although Rational numbers can be written as a decimal or fraction, it is actually a set of Real Numbers. The <span>displayed weights that shows each weight to the nearest half pound gives a terminating decimal number, thus it is best described by Real Numbers. </span>
