Question

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 63 N acts on a certain object, the acceleration of the object is 7 /ms2. If the acceleration of the object becomes 2nd /ms2, what is the force?

Answer 1

Answer:

18 N

Step-by-step explanation:

Let F denote the force, m denote the mass of the object and a denote the acceleration of the object.

$F=ma$

$m = \frac{F_{1} }{a_{1} }=\frac{63}{7} =9 kg$

$F_{2} =ma_{2}=9*2=18N$
