Question

A car moves with velocity 10 m/s towards east in 5s,its velocity changes to 10m/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 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
