Answer:
3 m/s²
Explanation:
We can use Newton's Second Law of Motion. The Second Law of Motion states that acceleration is calculated by dividing the force by the mass.
with f being the force and m being the mass
We know that the force is 1,500 N and the mass is 500 kg.
So, let's substitute:

So the acceleration of the cart is 3 m/s²
Hope this helps :)
