A car starts from rest and moves along the path OAB as shown. It moves with a speed of 35 miles per hour along OA and 50 miles per hour along AB.

Which of the following is true about the car's velocity?

The velocity of the car remains constant throughout the journey.

The velocity of the car changes due to the change in speed and direction.

The change in direction alone causes the velocity of the car to vary.

The change in speed alone causes the velocity of the car to vary.

1. no way to tell, since you do not say whether the direction changed.
But it's clearly not A.
