Question

I) Answer question numbers (a) - (d) on the basis of your understanding of the

Following paragraph and the related studied topics.

The movement of objects can be described using motion graphs and numerical values. These are both used to help in the design of faster and more efficient vehicles. For a moving object, the velocity can be represented by a velocity-time graph. A horizontal line on a velocity-time graph, shows that the object is at constant velocity, but a sloping line on a velocity-time graph, shows that the object is accelerating. The gradient of the line is equal to the acceleration of the object. Analyze the given graphs answer the following questions.

a) Which of the following row show what each section of the line on the Graph – 1 represent correctly?

Section of graph Velocity Acceleration

A.

A increasing positive

B.

B constant positive

C.

C constant negative

D.

D zero (at rest) negative

b) In the V-T graph for the cyclist, which part represents that the cyclist is traveling at constant speed

A. A

B. B

C. C

D. D

c) Calculate the distance travelled by the cyclist in the first 5 seconds.

A. 30 m

B. 35 m

C. 40 m

D. 50 m
