Question
A. 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].
• Calculate the force of gravity on the rock and the normal force of the ground on the rock.
• Calculate the force of gravity on the rock and the normal force of the ground on the rock.

To calculate the force of gravity on the rock, we use the formula:
Force of gravity = mass x gravity
Given:
Mass = 150 kg
Gravity = 9.81 m/s^2
Force of gravity = 150 kg x 9.81 m/s^2
Force of gravity = 1471.5 N
Now, to calculate the normal force of the ground on the rock, we need to consider the vertical forces acting on the rock.
Vertical forces:
- Force of gravity acting downwards = 1471.5 N
- Normal force acting upwards (opposing force of gravity)
Since the rock is on a horizontal surface, the normal force is equal in magnitude but opposite in direction to the force of gravity. Therefore, the normal force is also 1471.5 N.
