Question

For a moving object, the force is acting on the object varies directly with the object’s acceleration. When a force of 9 N acts on a certain object, the acceleration of the object is 3 m/s^2. If the acceleration of the object becomes 4 m/s^2, what is the force?

Answer 1

12 Newtons

Explanation:

We can use Newton’s Second Law to find the mass first.

F = ma

9 = 3m

mass = 3

Substitute this into the second equation.

F = ma

F = 3(4)

F = 12N

Hope this helps! :D
