sweet [91]

Answer:

The answer is 306 m/s^2

Explanation:

F = m*a

We can rearrange this formula to get a = F / m.

The SI unit for mass is kilograms (kg).

The SI unit for acceleration is m/s^2.

There are 1000 grams in a kilogram.

7.20 g = 0.00720 kg

Force (2.20 N) / 0.00720 kg = 305.56 m/s^2

Accounting for Sig Figs, the answer is 306 m/s^2.

Gee, that's one fast bullet.
