For a moving object, the force acting on the object varies directly with the object's acceleration. when a force of 15 n acts on a certain object, the acceleration of the object is 5 /ms2. if the acceleration of the object becomes 9 /ms2, what is the force?

27 N

Step-by-step explanation:

Since force varies directly with acceleration, we can introduce a constant, k, and write  

When force is 15, acceleration is 5, so plug it into the equation and solve for k:

Now, to find force, we use a = 9 and k = 3, so

The force is 27 N

x = -2

y = 848
