Question 11
2 marks · Normal
Answer and see the solution →A train travels at an average speed of 30 m/s. How far does it travel in 12 minutes? Give your answer in kilometres.
Question 12
1 mark · Normal
Answer and see the solution →State the SI unit for speed.
Question 13
2 marks · Normal
Answer and see the solution →Describe one way you could measure the speed of a rolling ball in the laboratory, using equipment available in your school.
Question 14
5 marks · Normal
Answer and see the solution →A student times a remote-control car moving along a straight track. The car starts from rest at point A and moves at a steady speed until it reaches point B, 40 m away. It takes 25 seconds to get from A to B.
(a)[2 marks]Calculate the average speed of the car as it moves from A to B. Give your answer in m/s.
(b)[3 marks]After stopping at B for 15 seconds, the car returns with the same average speed to A. Draw the distance–time graph for the whole journey from A to B to A, labelling axes with units and marking the time points where the car changes direction or is stationary.
Question 15
2 marks · Normal
Answer and see the solution →State two features of a distance–time graph that show an object is moving with constant speed.
Question 16
3 marks · Normal
Answer and see the solution →A cyclist travels a total distance of 6.3 km in 14 minutes. Calculate the cyclist’s average speed in m/s. Give your answer to 2 decimal places.
Question 17
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 18
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.
