A race car starts from rest and speed up uniformly to the right until it reaches a maximum velocity of 60m/s in 15 sec

The magnitude of a velocity vector is called speed. suppose that a wind is blowing from the direction n45°w at a speed of 40 km/h. (this means that the direction from which the wind blows is 45° west of the northerly direction.
