Answer:
Amount of linear movement
Explanation:
Our system is defined by the rate of change in mass that
leaves the car , this happens during a time interval
, in addition to freight car and sand at time t.
In this way we need to define the two states:
State 1,
consider and V.
State 2,
consider
In this state is the mass of sand output, which
is composed of
In this way we define the Linear movement in x, like this:
In this way we proceed to obtain the Force
Since the mass of the second term becomes 0, the same term is eliminated, thus,
