Answer and see the solution →A ball rolls down a ramp, starting from rest. The velocity–time graph for the first 4 seconds is a straight line from (0, 0) to (4, 8).
(a)[1 mark]Draw the velocity–time graph for this motion, labelling both axes with appropriate units.
(b)[1 mark]Explain how you would use the area under the graph to find the distance travelled in these 4 seconds.
(c)[2 marks]Calculate the distance the ball rolls in the 4 seconds.
Question 63
2 marks · Easy
Answer and see the solution →Explain why the area under a velocity–time graph is sometimes a triangle and sometimes a rectangle. Give an example of each case.
Question 64
2 marks · Easy
Answer and see the solution →A walker starts at 2 m/s and walks at this speed for 6 seconds, then stops instantly. Calculate the total distance travelled, and state which shape under the velocity–time graph you used.
Question 65
4 marks · Normal
Answer and see the solution →A sprinter runs a race. The velocity–time graph below shows her motion for the first 8 seconds of the race.
Figure 1. Sprinter's velocity-time graph (a)[3 marks]Calculate the total distance the sprinter travels in the first 8 seconds.
(b)[1 mark]Explain how the area under the graph represents the distance travelled.
Question 66
2 marks · Normal
Answer and see the solution →A cyclist moves at a constant velocity of 6 m/s for 35 seconds. Calculate the distance travelled using the area under the velocity–time graph.
Question 67
3 marks · Normal
Answer and see the solution →The graph shows the motion of a car as it accelerates uniformly from rest to 18 m/s in 6 seconds.
Figure 2. Velocity-time graph for a car accelerating (a)[2 marks]Calculate the total distance the car travels in the first 6 seconds.
(b)[1 mark]State the shape formed under the graph and briefly describe how you found the distance.
Question 68
3 marks · Normal
Answer and see the solution →A runner moves at first with increasing speed, then at a steady speed, and finally slows to a stop. Describe how her velocity–time graph would look, and explain how you would calculate the total distance travelled from the graph.
Question 69
2 marks · Normal
Answer and see the solution →What does the area under a velocity–time graph represent? Give an example of how you could find it for an object moving at constant velocity.
Question 70
5 marks · Hard
Answer and see the solution →The velocity–time graph below shows the motion of an object moving in a straight line over 12 seconds.
Velocity–time graph for an object (a)[4 marks]Calculate the total distance travelled by the object during the 12 seconds. Show your working using the area under the graph.
(b)[1 mark]Explain why the total distance travelled and the displacement of the object are equal or not equal for this motion.
