If a force accelerates 4.5 kg at 40 m/s ^2, that same force would accelerate 18 kg how much?

Force equals mass times acceleration! (F= ma)

If m= 4.5 kg and a= 10 m/s2, what is F?

Now, using that same force, but m= 18kg, solve F= ma for a.

A slightly more sophisticated method is to say m1a1= F= m2a2.

That is (4.5)(10)= (18)(a).
