Question 13
3 marks · Normal
Answer and see the solution →A car travels at a constant speed of 20 m/s north and then turns to travel 20 m/s east. Explain how its speed and velocity change.
Question 14
4 marks · Normal
Answer and see the solution →A runner accelerates from rest to a speed of 6 m/s in 3 s.
(a)[1 mark]State the initial velocity of the runner.
(b)[2 marks]Calculate the acceleration.
(c)[1 mark]State the SI unit for acceleration.
Question 15
3 marks · Normal
Answer and see the solution →A car slows down from 18 m/s to 6 m/s in 4 seconds. Calculate its acceleration.
Question 16
2 marks · Normal
Answer and see the solution →Explain why velocity is a vector quantity but speed is a scalar quantity.
Question 17
4 marks · Normal
Answer and see the solution →A boat travels at a constant speed of 5 m/s across a river that is 100 m wide. The current flows east at 3 m/s, and the boat points directly north (perpendicular to the current).
Explain the difference between the speed of the boat and its velocity as it crosses the river. Give your answer in terms of scalar and vector quantities, and describe the actual path of the boat across the river.
Question 18

Answer and see the solution →The table below shows the velocity of a cyclist during a 10-second journey:
Time / s Velocity / m/s 0 0 2 4 4 8 6 8 8 4 10 0 Use the information to answer the following questions.
(a)On graph paper, draw a velocity–time graph for the cyclist's journey. Label your axes.
(b)[2 marks]Describe the motion of the cyclist between 2 s and 6 s.
(b)[2 marks]Describe the motion of the cyclist between 2 s and 6 s.
Question 19
1 mark · Normal
Answer and see the solution →State what the gradient of a velocity–time graph represents.
Question 20
2 marks · Normal
Answer and see the solution →The velocity–time graph of a car shows that its velocity increases from 5 m/s to 25 m/s in 10 s. Calculate the acceleration of the car.
