For a moving object, the force acting on the object varies directly with the objects acceleration. when the force of 81 n acts in a certain object, the acceleration of the object is 9/ms^2. if the force is changed to 63n. what will be the acceleration of the object?

Step-by-step explanation:

It is given that,

For a moving object, the force acting on the object varies directly with the objects acceleration.

When the force of 81 N acts in a certain object, the acceleration of the object is 9/ms^2.

......(1)

If the force is 63 N then,

......(2)

On solving equation (1) and (2), we get :

So, the acceleration of the object is when the force acting on it is 63 N. Hence, this is the required solution.
