A body moves in a straight line with speed \(v_1\) and \(v_2\) for distance which are in ratio \(1: 2\). Find the average speed.
- A \(3 v_1+v_2\)
- B \(v_2+2 v_1\)
- C \(\frac{3 v_1 v_2}{v_2+2 v_1}\)
- D \(\frac{3 v_1 v_2}{v_2-2 v_2}\)
Answer & Solution
Correct Answer
(C) \(\frac{3 v_1 v_2}{v_2+2 v_1}\)
Step-by-step Solution
Detailed explanation
Given that, the distances travelled by the body are in ratio \(1: 2\). Let us suppose that \(s\) is the distance, the body travels with speed \(v_1\). Then, \(2 s\) will be the distance travelled by the body with speed \(v_2\). This scenario is shown in the line-diagram below…
