In physics class, Carrie learns that a force, G, is equal to the mass of an object, m, times its acceleration, a. She writes the
wlad13 [49]

Your problem statement is missing the formula Carrie came up with. It should be The one she started with, divided by m.

... G/m = a

For the values given, the acceleration is

... (7.92 N)/(3.6 kg) = 2.2 m/s²

_____

The unit of newtons is abbreviated N.

1 N = 1 kg·m/s² so dividing by kilograms leaves units of m/s², which are the units of acceleration.

Very likely, your question is not concerned with the units, just the number: 2.2. It's a straight division problem, easily handled by hand, by calculator, or in your head (after you realize 7.92 = 7.2×1.1 = 2×3.6×1.1).
