Question 71
4 marks · Hard
Answer and see the solution →A trolley starts from rest and accelerates steadily. After 2 s, its velocity is 4 m/s, and after a further 3 s, its velocity is 10 m/s.
(a)[2 marks]Sketch a velocity–time graph for the motion of the trolley for the first 5 seconds.
(b)[2 marks]Calculate the total distance travelled by the trolley in 5 seconds by finding the total area under the velocity–time graph.
Question 72
4 marks · Hard
Answer and see the solution →A go-kart travels with constant velocity for 2 seconds, then slows down uniformly to a stop in the next 3 seconds.
(a)[2 marks]The initial velocity is 8 m/s. Draw a labelled velocity–time graph for the go-kart’s motion over the 5 seconds.
(b)[2 marks]Using your graph, calculate the total distance travelled by the go-kart during the 5 seconds. Show your working.
Question 73
2 marks · Easy
Answer and see the solution →A child on a scooter starts from rest and accelerates uniformly at 2 m/s² over a distance of 8 m. Calculate the speed she is travelling at the end of the 8 m.
Question 74
2 marks · Easy
Answer and see the solution →A physics student says: “If an object travels with constant acceleration, you can always use the equation to solve for any one of the variables.” Explain one limitation of this equation in solving real-life motion problems.
Question 75
3 marks · Easy
Answer and see the solution →A skateboarder moves in a straight line. She starts at 3 m/s and accelerates uniformly at 1.5 m/s² for 4 m.
(a)[1 mark]State the initial speed of the skateboarder.
(b)[2 marks]Calculate her final speed after travelling the 4 m.
Question 76
2 marks · Easy
Answer and see the solution →Describe what is meant by ‘initial speed’ and ‘final speed’ in the equation .
Question 77
2 marks · Easy
Answer and see the solution →A cyclist slows down uniformly from 14 m/s to 8 m/s over a distance of 33 m. Calculate her acceleration.
Question 78
1 mark · Easy
Answer and see the solution →Write down the full equation relating final speed (v), initial speed (u), acceleration (a), and distance moved (s) for uniform acceleration.
Question 79
3 marks · Easy
Answer and see the solution →Describe how you would investigate the motion of a toy car rolling down a ramp, to see if it accelerates uniformly.
