When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 4 kg, the acceleration of the object is 5 /ms2. If the same force acts upon another object whose mass is 10 kg, what is this object's acceleration?

Step-by-step explanation:

Knowing that being the mass and the acceleration we have:

"When a certain constant force acts upon an object with mass 4kg the acceleration of the object is "

We can calculate that force as:

Now, that force is being aplied to another objet whose mass is 10 Kg and we want to know its acceleration.

Clearing from the force equation we have:

 ("The acceleration of the object varies inversely with its mass")

Then,

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
