You've got a slight mix-up in the units! Acceleration is measured in meters per second squared (m/s²), not meters cubed (m³).

Here's how to calculate the force needed:

Newton's Second Law of Motion

The force needed to accelerate an object is calculated using the following formula:

* Force (F) = Mass (m) x Acceleration (a)

Applying the Formula

* Mass (m) = 2000 kg

* Acceleration (a) = 1.5 m/s²

* Force (F) = 2000 kg * 1.5 m/s² = 3000 Newtons (N)

Therefore, a force of 3000 Newtons is needed to give a 2000 kg car an acceleration of 1.5 m/s².
