To calculate the force of gravity on the rock, we can use the equation:
Force of gravity = mass x acceleration due to gravity
Given that the mass of the rock is 150 kg, and the acceleration due to gravity is approximately 9.8 m/s^2, we can calculate:
Force of gravity = 150 kg x 9.8 m/s^2 = 1470 N
Therefore, the force of gravity on the rock is 1470 N.
To find the acceleration of the rock, we need to consider the net force acting on it. The net force is the difference between the force applied by the tractor and the force of friction:
Net force = Force applied - Force of friction
Net force = 1200 N - 750 N
Net force = 450 N
Now we can use the equation F = ma (Newton's second law) to find the acceleration:
450 N = 150 kg x a
a = 450 N / 150 kg
a = 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].
