To find the normal force of the ground on the rock, we need to consider the forces acting on the rock in the vertical direction.
The vertical forces acting on the rock are the weight of the rock and the normal force of the ground on the rock. Since there is no vertical acceleration, these forces must balance each other out.
Weight of the rock = mg
= 150 kg * 9.8 m/s^2
= 1470 N
Since the normal force opposes the weight of the rock, the normal force is equal in magnitude but opposite in direction to the weight of the rock. Therefore, the normal force is 1470 N.
So, the normal force of the ground on the rock is 1470 N.
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].
