Answer:
5 m/s2, left
Explanation:
We can solve the problem by applying Newton's second law of motion, which states that:
where:
is the net force acting on an object
m is the mass of the object
a is its acceleration
In this problem, we have:
(to the left) is the net force on the object
m = 2.0 kg is the mass
So, the acceleration is:
in the same direction as the force (left).
