A car moves with velocity 10 m/s towards East in5 s, its velocity changes to 10 m/s towards North.Then the change in velocity of car is |
|
Answer» The change in velocity of the car is 10√2 m/s Explanation: According to the problem the velocity of the car while MOVING towards EAST was 10 m/s The velocity of the car while moving towards North is 10 m/s The direction as well as velocity changes after 5 s Now the change in velocity will be: √(INITIAL velocity)^2 + (final velocity)^2 = √ (10)^2 + (10)^2 = √ 100 + 100 = 10√2 m/s |
