Igcse Model Questions Vol1 2020 Physics Question 32 diagram

The diagram shows a motion diagram of a particle moving in a straight line. The marks are taken at equal time intervals of 0.5 s and the recorded positions are 0 m, 1.5 m, 3.5 m, 6 m and 9 m measured from the start point. Using the diagram, determine (a) the average speed of the particle between the first and last marks, (b) the instantaneous speed during the third interval (between the second and third marks), and (c) state whether the particle's motion is uniformly accelerated.

Answer Options

A. Average speed = 4.5 m\/s; instantaneous speed in third interval = 5.0 m\/s; motion is not uniformly accelerated.
B. Average speed = 4.5 m\/s; instantaneous speed in third interval = 6.0 m\/s; motion is uniformly accelerated.
C. Average speed = 3.5 m\/s; instantaneous speed in third interval = 4.0 m\/s; motion is uniformly accelerated.
Correct Answer D. Average speed = 4.5 m/s; instantaneous speed in third interval = 5.0 m/s; motion is uniformly accelerated.
Correct Answer
D
Correct Option:
Average speed = 4.5 m/s; instantaneous speed in third interval = 5.0 m/s; motion is uniformly accelerated.
