Motion in A Straight Line question

2009 · Q153

NEETPhysicsMotion in A Straight LineMCQ+4 / −1
A bus is moving with a speed of 10 ms−-−1 on a straight road. A scooterist wishes to overtake the bus in 100 s. If the bus is at a distance of 1 km from the scooterist, with what speed should the scooterist chase the bus ?
  1. A
    40 m s−-−1
  2. B
    25 m s−-−1
  3. C
    10 m s−-−1
  4. D
    20 m s−-−1
View written solutionFree

Correct answer: D

Relative velocity of the scooter with respect to the bus = (vs - 10)

∴\therefore∴ 1000vs−10{{1000} \over {{v_s} - 10}}vs​−101000​ = 100

⇒\Rightarrow⇒ vs = 20 m/s
