A car travels along a road. The force on the car due to the engine is 800 N. The motion of the car depends on the value of the total resistive force R. [Figure 7.1] Which row shows the motion of the car for the given value of R?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Avalue of resistive force R/N: 500, motion: deceleration
Bvalue of resistive force R/N: 800, motion: acceleration
Cvalue of resistive force R/N: 900, motion: deceleration
Dvalue of resistive force R/N: 1000, motion: acceleration
✓ Correct answer
C: value of resistive force R/N: 900, motion: deceleration
