8. If a car's engine exerts a bigger force forwards than the drag force backwards, what will happen?

  • The car will stop
  • The car will accelerate
  • The car will travel at a constant speed
  • The car will slow down
  • The car will travel forwards

9. Jet Aircraft part A. - If a jet aircraft is moving at a constant speed and altitude, what factor applies to all of the forces?

  • The acting forces are constant
  • The counter forces are greater to allow the aircraft to travel
  • The resultant forces are equal to the relevent acting forces
  • The counter forces are lower

10. Jet Aircraft part B. - Accordingly to part A. If the weight of the aircraft is 250,000N, what is the upwards force (the lift)

  • Lower
  • Equal - 250,000N
