Answer:
20 N
Explanation:
We can solve this problem by applying Newton's second law of motion, which states that the net force applied on an object is equal to the product between the mass of the object and its acceleration:
[tex]F=ma[/tex]
where
F is the net force
m is the mass
a is the acceleration
In this problem, we have:
m = 10 kg is the mass of the cart
[tex]a=2 m/s^2[/tex] is the acceleration
So the net force on the car is
[tex]F=(10)(2)=20 N[/tex]
Since Lucia and Akbar are pushing into opposite directions, this means that this net force is the resultant of the two forces: and since the cart is accelerating towards Akbar, this means that Lucia is applying a force 20 N stronger than Akbar.
