pramod travelled from pune to mumbai (consider the path is straight) which is 150 km apart on 5 may now on next day he travelled from mumbai to pune and return back to lonavala which is 90 km away from mumbai on same path for tge journey on 5,may he covered 150 kn distance in 3 hrs. a. ) for 5may journey calculate distance and displacement from pune to mumbai. b.) what is velocity c) for 6,may journey calculate distance and displacement P for complete travelling. d) compare speed and velocity. e) define displacement
Answers
For 5thmay journey, the distance and displacement from Pune to Mumbai are both 150kms.
1. Velocity is defined as the rate of displacement. For instance in the above case as displacement is 150kms. So he covered this displacement in 3hrs. So velocity=(Displacement/time)=150/3=50 kmph.
2. For 6,may journey, distance and displacement P for complete traveling are 210kms and 90kms respectively.
3. speed and velocity comparision. Speed is rate of distance travelled and Velocity is Rate of shortest distance or displacement. Speed is a scalar as it doesn't have any specific direction. Velocity is vector quantity as it is directed towards start to end.
4. Displacement is defined as the shortest distance or distance between the start point and ened point. The displacement is the distance between the start and end point (Start point-Mumbai and end point is Lonavala. Distance between them is 90kms)
