Answer:
5 m/s2, left
Explanation:
We can solve the problem by applying Newton's second law of motion, which states that:
[tex]\sum F=ma[/tex]
where:
[tex]\sum F[/tex] is the net force acting on an object
m is the mass of the object
a is its acceleration
In this problem, we have:
[tex]\sum F=30 N - 20 N = 10 N[/tex] (to the left) is the net force on the object
m = 2.0 kg is the mass
So, the acceleration is:
[tex]a=\frac{\sum F}{m}=\frac{10}{2.0}=5.0 m/s^2[/tex]
in the same direction as the force (left).
