A car traveling towards east at 40 m/s and turns towards left and travels at same speed. The change in velocity is

Explanation:

In physics the term velocity is always a vector.  All that means is that it's got a direction with it.  which also means this vehicle that was traveling in the east direction and then turned left is and is now ,  maybe traveling in a north direction.  Making the guesses that the car was traveling due East and is now traveling due North, then the car has changed it's velocity by 40 m/s.  By The Way do you happen to know how fast 40 m/s is?  it's about 144 Kph  :0  or about 90 MPH    so this guy is also speeding  :D,  write him a ticket ... :P
