An applied force applied causes a body such as the spacecraft to move. The magnitude of the force determines the change in the velocity
What will happen to the spacecraft is given by option C. from among the possible question options.
C. The spacecraft will begin to move and it will continue moving until it is stopped by an equal and opposite force
Reason:
<em>The possible question options obtained from a similar question includes;</em>
<em>A. The spacecraft will move for some time then stop slowly</em>
<em>B. Air resistance will prevent the spacecraft from moving</em>
<em>C. The spacecraft will begin to move and the motion will continue until a force equal and opposite to the applied force stops it</em>
<em>D. The quick push will not cause the spacecraft to move, as a quick push works on Earth only</em>
The state of the space craft = Motionless
Location of the spacecraft = Deep space
Type of force applied = Quick push
The statement that describes what will happen = Required
Solution;
Let <em>F</em>, represent the force applied, and let Δt be the duration of the applied force, we have;
The impulse of the force, F × Δt = m·(v₂ - v₁)
Where;
m = The mass of the spacecraft
v₁ = The initial velocity of the spacecraft = 0
v₂ = Final velocity of the spacecraft
Plugging in v₁ = 0, gives;
F × Δt = m·v₂
The space craft is given a velocity, <em>v₂</em>, and according to Newton's First Law of Motion, it continues moving in a straight line until another force acts on it
Therefore, the correct option is option C. <u>The spacecraft will begin to move and the motion will continue until it is stopped by an equal and opposite force</u>
