To find the acceleration of the rock, we first need to calculate the net force acting on the rock.
Net force = Force pulling to the right - Force of friction
Net force = 1200 N - 750 N
Net force = 450 N
Next, we can use Newton's second law of motion to find the acceleration of the rock:
Net force = mass * acceleration
450 N = 150 kg * acceleration
Now, solve for acceleration:
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].
• find the acceleration of the rock.
