c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

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
