The net force on the rocket is directed upward with a magnitude of
35 N - 25 N = 10 N
By Newton's second law, the acceleration <em>a</em> is such that net force is equal to the mass of the rocket times its acceleration:
10 N = (2.5 kg) <em>a</em>
<em>a</em> = (10 N) / (2.5 kg)
<em>a</em> = 4 m/s²
Use the elimination method.
(-5x + y = 26)7
2x - 7y = 16
-35x + 7y = 182
2x - 7y = 16
-33x = 198
x = -6
Substitiute -6 for x in one of the equations.
2x -7y = 16
2(-6) - 7y = 16
-12 - 7y =16
-7y = 28
y = -4
The ordered pair would be (-6,-4)
Answer: A=-2
Step-by-step explanation:
AB=11
B=9
B-11=A
9-11=A
A=-2
