Answer» 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 is 10 m/s. The velocity of the car while moving towards North is 10 m/s The change in direction TOOK place after 5 sec Therefore the change is velocity is: √(INITIAL velocity)^2 + (final velocity)^2 = √(10)^2 + (10)^2 = 10√2 m/s Hence the answer is 10√2 m/s |
