There seems to be a slight error in the question. Acceleration is measured in meters per second squared (m/s²), not meters per second (m/s).

Assuming you meant an acceleration of 1.5 m/s², we can use Newton's second law of motion to calculate the force:

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

* Mass (m) = 2000 kg

* Acceleration (a) = 1.5 m/s²

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.
