5.
How can Newton's law of action-reaction best be applied to explain the movement of a rocket?
a)
As the fuel burns, gasses push against the rocket, moving it upward
b)
As the fuel burns, gases move out of the rocket and reduced air pressure.
c)
As the fuel burns, the mass of the rocked decreases.

6.
The total mass of the cyclist and the bicycle is 100.0kg. Based on this information, what is the acceleration of the cyclist?
a)
0.66 m/s2 backward, because the force of the air slows the cyclist down.
b)
0.66 m/s2 forward, because the applied force is greater than the force of the air
c)
2.3 m/s2 backward, because the forces are opposite and not equal.
d)
2.3 m/s2 forward, because the cyclist inertia is greater than the force of the air.

a)
North
b)
South
c)
East
d)
West
