You're very close to the right idea, but there's a slight misunderstanding. Acceleration is measured in meters per second squared (m/s²), not just meters (m).

Here's how to calculate the force:

Newton's Second Law of Motion:

* F = m * a

Where:

* F is the force (in Newtons)

* m is the mass (in kilograms)

* a is the acceleration (in meters per second squared)

Let's plug in the values:

* m = 1500 kg

* a = 3 m/s²

F = 1500 kg * 3 m/s² = 4500 N

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