When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with a mass of 4 kg, the acceleration of the object is 7 m/s 2. When the same force acts upon another object, it’s acceleration is 2 m/s. What is the mass of this object

First:

F=m.a

=4*7

=28N

Second:

F=m.a

28=m.2. (force is constant,so F=28N)

28/2=m

m=14kg.

First:

F=m.a

=4*7

=28N

Second:

F=m.a

28=m.2. (force is constant,so F=28N)

28/2=m

m=14kg.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
