Which of the following groups of elements are in the main group? A. Nonmetals
B. Transition elements
C. Alkali metals

D. Halogens

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
