3.375m/s is the final velocity of the car.
<h3>How do you find final velocity?</h3>The final velocity depends on how large the acceleration is and the distance over which it acts.
Initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity.
According to the question,
A toy car starts from the rest and accelerates
So the acceleration = 1.50m/s²
Time = 2.25s
The final velocity, of the car is 3.375 m/s.
