First, we need to calculate the net force acting on the rock. The net force can be calculated by subtracting the force of friction from the force applied by the tractor:
Net force = 1200 N - 750 N = 450 N
Next, we can calculate the acceleration using Newton's second law, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass:
Acceleration = Net force / Mass
Acceleration = 450 N / 150 kg
Acceleration = 3 m/s^2
Therefore, the acceleration of the rock is 3 m/s^2.
A tractor pulls a 150 kg rock to the right with a force of 1200 N against a force of friction of 750 N [left].
