You're asking about the force needed to move a 1500 kg vehicle with an acceleration of 3 m/s². (Acceleration is measured in meters per second squared, not just meters).

Here's how to calculate the force using Newton's Second Law of Motion:

* Newton's Second Law: F = m * a

* F = Force (in Newtons)

* m = Mass (in kilograms)

* a = Acceleration (in meters per second squared)

Calculation:

* F = 1500 kg * 3 m/s²

* F = 4500 N

Therefore, a force of 4500 Newtons is needed to move a 1500 kg vehicle at an acceleration of 3 m/s².
