Question

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of45N

acts on a certain object, the acceleration of the object is5m/s∧2
. If the force is changed to81N
, what will be the acceleration of the object?

Answer 1

9

Step-by-step explanation:

the force is directly proportional to acceleration

F=ma

F1/a1=F2/a2

45/5=81/a2

81×5/45=9M/S²
