Procedures <em><u>point C</u></em> could be used to determine how the mass of the fan-car-object system affects the acceleration of the system
<h3>Further explanation </h3>Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object
<h3>∑F = m. a </h3>F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
we complete the available answer choices
A).Measure the mass of the system using a balance, activate the fan, measure the distance traveled by the system at a known time by using a stopwatch, and repeat the experiment for several trials with different objects added to the carriage.
B) Measure the mass of the system using a balance, activate the fan, use a meterstick and stopwatch to measure the initial and final speeds of the system, and repeat the experiment for several trials with different objects added to the carriage.
C)Measure the mass of the system using a balance, connect a spring scale to the back of the car, measure the amount of force required to hold the system at rest, and repeat the experiment for several trials with different objects added to the carriage.
D)Measure the mass of the system using a balance, activate the fan, use a stopwatch to record the time it takes for the system to travel before the battery of the fan no longer works, and repeat the experiment for several trials with different objects added to the carriage.
From the choices above, we choose point C because to find out the effect of mass on acceleration, we need the force value (F) from the spring scale and the mass of objects of different masses using a balance
If we look at the formula, we can analyze and estimate that the greater the mass given, the smaller the system acceleration

The woman's average velocity can be calculated by dividing the total distance covered during the motion by the total time of the motion.
In the first part of the motion, the woman moved south with speed v1=2.00 m/s for a time of
therefore the distance she covered is
In the second part of the motion, she moved north for
in a time of
Since she moved in the opposite direction, the total distance covered is the difference between S1 and S2:
(south)
While the total time of the motion is
Therefore, the woman's average velocity is
(south)
and the correct answer is A).
