Question 101
3 marks · Hard
Answer and see the solution →A car is moving at a constant speed. The driver sees a red traffic light 120 m ahead and applies the brakes after 3 seconds. The car slows down uniformly and stops 10 seconds later, right at the light.
(a)[2 marks]Sketch a distance–time graph for the entire journey from the point where the driver sees the red light until the car stops (from 0 to 13 seconds). Label the axes and mark clearly when the car starts braking.
(b)[1 mark]State and explain how the slope of the graph changes during the braking period.
Question 102
3 marks · Hard
Answer and see the solution →A group of students investigate how a trolley moves down a ramp. They record the time taken for the trolley to travel different distances starting from rest.
Results collected by the students. Distance (m) Time (s) 0.5 2.0 1.0 2.8 1.5 3.4 (a)[2 marks]Using the table, calculate the average speed of the trolley between 0.5 m and 1.5 m.
(b)[1 mark]Explain why the average speed increases as the distance increases.
Question 103

Question 108
2 marks · Easy
Answer and see the solution →An athlete runs around a circular track at constant speed. Explain why the athlete’s velocity is not constant.
Question 109
2 marks · Easy
Answer and see the solution →A car’s velocity changes from +15 m/s to -5 m/s in 10 seconds. What does the negative sign mean in this context? State your answer clearly.
Question 110
1 mark · Easy
Answer and see the solution →Write the equation linking acceleration, initial velocity, final velocity, and time.
