A heavy person and a light person parachute together and wear the same size parachutes. Assuming they open their parachutes at the same time, which person reaches the ground first?

A. the light person	

B. the heavy person	

C. Neither -- they both reach the ground together.	

I chose B.

The first is B because you would have to over come static friction that it 10 times greater than the smaller brick, and the second is C. Because two objects regardless of weight and ignoring air resistance will wall at the same rate

You need Newtons second law, F=ma, where 'F' is the force required to accelerate a mass 'm' with magnitude 'a'.
If you want to give two objects the same acceleration, lets call it 'A', and the masses of the two objects are M and 10M, then:
$$F_1=MA$$
$$F_2=10MA$$
you can see that
$$F_2=10F_1$$
