Question 41
6 marks · Normal
Answer and see the solution →A cyclist travels along a straight road. The distance–time graph for her first 10 seconds is shown below.
(a)Distance-time graph for a cyclist. (i)[1 mark]Describe how the cyclist’s speed changes during the time shown.
(ii)[1 mark]Calculate the average speed of the cyclist during the first 8 seconds.
(b)[2 marks]Using your answer to part a(ii), explain whether the cyclist’s average speed is the same as her speed at 10 s.
(c)[2 marks]State whether the graph shows negative, zero, or positive acceleration during the interval 8 s to 10 s. Explain your answer.
Question 42

Answer and see the solution →A student uses a toy car to investigate acceleration down a track. The results are shown in the table.
Measured velocity of the toy car at different times. Time (s) Velocity (m/s) 0.0 0.0 1.0 2.0 2.0 4.0 3.0 6.0 4.0 8.0 (a)[2 marks]Plot a velocity–time graph for the results above. Label each axis.
(b)[2 marks]Determine the gradient of the velocity–time graph. State what this gradient represents.
(c)[2 marks]Calculate the distance travelled by the car in the first 4 seconds using your graph or the area method.
Question 43

Answer and see the solution →A car starts at rest, accelerates uniformly to a speed of 20 m/s in 4 seconds, then travels at constant speed for 6 seconds.
(a)[2 marks]Draw a labelled velocity–time graph for the motion of the car from 0 to 10 seconds.
(b)[1 mark]Calculate the acceleration during the first 4 seconds.
(c)[2 marks]Calculate the total distance travelled in the 10 seconds.
Question 44

Answer and see the solution →The table shows the motion of a ball thrown vertically upwards. Air resistance is negligible.
Time (s) Velocity (m/s) 0.0 24.0 1.0 14.2 2.0 4.4 3.0 -5.4 4.0 -15.2 (a)[2 marks]Plot the velocity–time graph for the ball using the data given. Label both axes.
(b)[2 marks]Determine the acceleration acting on the ball.
(c)[2 marks]Calculate the distance the ball travels in the first 2 seconds.
Question 45
6 marks · Normal
Answer and see the solution →A car is initially travelling at 15 m/s. It accelerates uniformly at 4 m/s² for a certain time.
(a)[1 mark]Calculate the velocity of the car after 3 seconds.
(b)[2 marks]Calculate the distance the car travels during these 3 seconds.
(c)[2 marks]Sketch a velocity–time graph for the motion described above. Include numerical values for axes.
(d)[1 mark]Explain the physical meaning of the gradient and the area under the graph you have drawn.
