Answer: To determine the acceleration and direction of the mass, we need to consider the net force acting on the mass. The net force is calculated by subtracting the force to the right from the force to the left:
Net force = 20 N - 10 N = 10 N to the left
Using Newton's second law (F = ma), we can determine the acceleration of the mass:
a = F / m = 10 N / 25 kg = 0.4 m/s² to the left
So the direction of the acceleration and the net force are to the left, which means the mass will move to the left.
