To calculate the force of gravity on the rock, we need to use the formula:
Force of gravity = mass x acceleration due to gravity
Given:
mass = 150 kg
acceleration due to gravity = 9.8 m/s^2
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 calculate the normal force of the ground on the rock, we first need to calculate the net force acting on the rock:
Net force = force applied by the tractor - force of friction
Net force = 1200 N - 750 N = 450 N
Now, since the rock is not accelerating vertically, the normal force acting on the rock must be equal in magnitude but opposite in direction to the force of gravity. Therefore, the normal force will be:
Normal force = force of gravity = 1470 N
Therefore, 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].
• Calculate the force of gravity on the rock and the normal force of the ground on the rock.
