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 20 N results in an acceleration of 10 m/s2 . If the object's acceleration becomes 7 m/s2, what is the force?

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 20 N results in an acceleration of 10 m/s2 . If the object's acceleration becomes 7 m/s2, what is the force?
solution F1/F2 = a1/a2
given F1 =20N F2=? a1 =10 m/s2 a2 = 7m/s2
hence F2 = (F1 *a2)/a1 = 140/10 = 14 N
