Force and Gravity, is what i think it is.
Answer:2.67kgm/s cube
Explanation: density = mass ÷ volume = 400 ÷ 150
<h3>Newtons first law state that if a body is in motion it will be in motion and if a body is in rest it will tend to be in rest. This phenomena is also called INERTIA. Example: We tend to fall sideways when a car turn suddenly</h3>
Force = mass × accelaration
Force = 0.25Kg × 196 m/s²
Force = 49 Newtons
