A particle moves along a straight line along the xx-axis. Its position ( x\mathrm{x} ) versus time (t)(\mathrm{t}) graph is shown in the figure [ xx in meters and tt in seconds]. It's average speed during this motion is A particle moves along a straight line along the x -axis. Its position ( x ) versus time (t) graph is shown in the

Options

  1. A0.4 ms−10.4 \mathrm{~ms}^{-1}
  2. B1.0 ms−11.0 \mathrm{~ms}^{-1}
  3. C0.8 ms−10.8 \mathrm{~ms}^{-1}
  4. D0.6 ms−10.6 \mathrm{~ms}^{-1}

Correct answer

C. 0.8 ms−10.8 \mathrm{~ms}^{-1}

Step-by-step solution

 Average speed = Distance travelled  time =4m5s=0.8m/s\begin{aligned} & \text{ Average speed }=\frac{\text{ Distance travelled }}{\text{ time }} \\ & =\frac{4 \mathrm{ m}}{5 \mathrm{ s}}=0.8 \mathrm{ m} / \mathrm{s}\end{aligned}
