Question 105

A cyclist rides along a straight horizontal road, starting from rest.

A student models the whole of the cyclist's journey using the velocity-time graph below.

Figure for question 4

a.

The student's graph relies on one of the assumptions listed below. Write down the letter of that assumption.

(A) The acceleration of the cyclist is the same at every instant of the journey. (B) The acceleration of the cyclist is never zero. (C) The acceleration of the cyclist switches from one value to another in no time at all. (D) The acceleration of the cyclist increases steadily throughout the journey.

b.

Give one reason why a real cyclist could not behave in the way part (a) describes.
