The velocity time graph of a body moving in a straight line is shown in figure. The ratio of displacement to distance travelled by the body in time 0 to 8 s is
Options
- A8: 5
- B3: 5
- C5: 9
- D7: 4
Correct answer
C. 5: 9
Step-by-step solution
The displacement is the net area under the velocity-time graph, while distance is the total area taken as positive. From t = 0 to 2 s: displacement +6 m, distance 6 m. From t = 2 to 3 s: displacement -2 m, distance 2 m. The remaining segments follow similarly, yielding displacements of +4 , -2 , and +4 m, with distances of 4 , 2 , and 4 m respectively. The total displacement is 6 - 2 + 4 - 2 + 4 = 10 m. The total distance is 6 + 2 + 4 + 2 + 4 = 18 m. The ratio simplifies to 10:18 = 5:9 .
