Question

A car moves with velocity 10 m/s towards East in
5 s, its velocity changes to 10 m/s towards North.
Then the change in velocity of car is​

Answer 1

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
