NEETPhysicsMotion in A Straight LineMCQ+4 / −1
A bus is moving with a speed of 10 ms1 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 ?
- A40 m s1
- B25 m s1
- C10 m s1
- D20 m s1
View written solutionFree
Correct answer: D
Relative velocity of the scooter with respect to the bus = (vs - 10)
= 100
vs = 20 m/s
