AP EAMCET · PHYSICS · Motion In One Dimension
A particle moves along a straight line along the \(x\)-axis. Its position ( \(\mathrm{x}\) ) versus time \((\mathrm{t})\) graph is shown in the figure [ \(x\) in meters and \(t\) in seconds]. It's average speed during this motion is
- A \(0.4 \mathrm{~ms}^{-1}\)
- B \(1.0 \mathrm{~ms}^{-1}\)
- C \(0.8 \mathrm{~ms}^{-1}\)
- D \(0.6 \mathrm{~ms}^{-1}\)
Answer & Solution
Correct Answer
(C) \(0.8 \mathrm{~ms}^{-1}\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text { Average speed }=\frac{\text { Distance travelled }}{\text { time }} \\ & =\frac{4 \mathrm{~m}}{5 \mathrm{~s}}=0.8 \mathrm{~m} / \mathrm{s}\end{aligned}\)
