Problema Solution
According to Newton's Second Law of Motion, the force acting on an object varies directly with the object's acceleration. Suppose that a force of 40 N results in an acceleration of 8 m/s^2 . If the force is changed to 15 N , what will the object's acceleration become?
Answer provided by our tutors
let 'a' be the acceleration
the force acting on an object varies directly with the object's acceleration
we can write the following proportion
40/8 = 15/a
a = (8*15)/40
a = 3 m/s^2
the object's acceleration will become 3 m/s^2.
