Answer: The mass of the object is 10 kg
Step-by-step explanation:
According to Newton's second law of motion, the force
applied to an object with mass
is directly proportional to its acceleration
:
(1)
If we isolate
:
(2) This means the acceleration of the object varies inversely with its mass
Now, we are given the following data to calculate a constant force using (1):

(3)
(4)
(5)
If we apply this same force calulated in (4) in another object with an acceleration of
, its mass
will be:
(6)
(7)
Finding
:
This is the mass of the object
Answer:
Equivelant fractions.
Step-by-step explanation:
Ask your self..
How did the 1/3 become 7/21?
Its very simple multiply 1/3's numerator and denominator by 7
So its going to be.. 1 x 7 = 7
3 x 7 = 21
