AP EAMCET · PHYSICS · Motion In One Dimension
A bird is tossing (flying to and fro) between two cars moving towards each other on a straight road. One car has speed of \(54 \mathrm{kmh}^{-1}\) while the other has the speed of \(36 \mathrm{kmh}^{-1}\). The bird starts moving from first car towards
the other and is moving with the speed of \(36 \mathrm{kmh}^{-1}\) where the two cars were separated by \(36 \mathrm{~km}\). The total distance covered by the bird before the cars meet each other is
- A 14400 m
- B 1440 m
- C 244 m
- D 24400 m
Answer & Solution
Correct Answer
(A) 14400 m
Step-by-step Solution
Detailed explanation
The total time after the two cars which meet \[ =\frac{\text { Total distance }}{\text { Relative velocity of car w.r.t each other }} \] \[ T=\frac{36}{54+36} \Rightarrow T=\frac{36}{90}=0.4 h \] In this duration, the distance travel by bird…
