Question

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 40N acts on a certain object, the acceleration of the object is 5m/s^2. If the acceleration of the object becomes 6m/s^2, what is the force?

Answer 1

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.

Answer 2

63N

Explanation:

Its easy

use the equation

M=F/A
