Question

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 28 N acts on a certain

object, the acceleration of the object is 7 m/s². If the acceleration of the object becomes 3 m/s2, what is the force?

Answer 1

Explanation:

F=ma

28=7m

m=28/7=4

F=4a

when a=3 m/s²

F=4×3=12 N
