JEE Mains · Physics · STD 11 - 2. motion in straight line
The motion of an airplane is represented by velocity-time graph as shown below. The distance covered by airplane in the first 30.5 second is _______ km .
- A \(12\)
- B \(3\)
- C \(6\)
- D \(9\)
Answer & Solution
Correct Answer
(A) \(12\)
Step-by-step Solution
Detailed explanation
Distance = area under the graph \(\begin{aligned} d & =300 \times 2+400 \times 28.5 \\ & =600+114000 \\ & =12000 \mathrm{~m} \end{aligned}\)
