Answer:
aceleration doubles
Explanation:
From Newton's secon law, one has
F=m*a
where F is the force, m the mass and a the aceleration.
In general, if m becomes m/2, in order to have the same force,
the acceleration must be doubled:
[tex]F=m*a=\frac{m}{2} (2*a)[/tex]
In our particular case,
[tex]12=6*a=\frac{6}{2} (2*a)\\12=3(2*a)[/tex]
