The figure displays the graph of the x -coordinate of a particle travelling along the X-axis as a function of time. Determine the average velocity of the particle during the interval from 0 to 10 s in m/s .
Options
- A20
- B0
- C10
- D5
Correct answer
C. 10
Step-by-step solution
The average velocity of a particle is defined as the total displacement divided by the total time taken. From the given position-time graph: At t = 0 s , the initial position x₁ = 0 m . At t = 10 s , the final position x₂ = 100 m . The displacement of the particle during this time interval is: x = x₂ - x₁ = 100 m - 0 m = 100 m The time interval is: t = 10 s - 0 s = 10 s The average velocity v_ avg is: v_ avg = x t = 100 10 = 10 m/s
