The change in speed of this object is 3m/s
According to Newton's second law;
F = ma
F = mv/t
Given the following parameters
Force F = 8.0N
mass m = 16kg
time t = 4.0s
Required
speed v
Substitute the given parameters into the formula
v = Ft/m
v = 8 * 6/16
v = 48/16
v = 3m/s
Hence the change in speed of this object is 3m/s

<h2>
Answer: A system in which Newton's Laws are fulfilled</h2>
An inertial reference system is a reference system in which the principle of inertia is fulfilled, which is one of Newton's laws:
<em>"For a body to have acceleration, an external force must act on it"
</em>
In addition, the other Newton's laws of movement are fulfilled.
Therefore, the variation of the linear momentum of the system is equal to the actual forces on the system.
