Correct the following statement: The racing car rounds the turn at a constant velocity of 145 km/hr.

Change the word "velocity" to speed". The velocity IS changing because the direction of motion is changing.

Sure, here's the corrected statement: "The racing car rounds the turn at a constant velocity of 0 km/hr because it got bored and decided to take a nap instead."

The racing car rounds the turn at a constant speed of 145 km/hr.

The statement is incorrect. The racing car cannot round a turn at a constant velocity. When a car is moving on a curved path, it experiences a change in direction, which means its velocity is constantly changing. To correct the statement, we can say: "The racing car rounds the turn at a constant speed of 145 km/hr."

it doesnt matter it can be constant velocity.
