SUMMARY
In a tractor pulling contest, a 2300-kg tractor exerts a horizontal force of 7700 N to pull a 4900-kg sledge with an acceleration of 0.61 m/s². The force of the tractor on the sledge is calculated using Newton's second law, resulting in a force of 4900 N. According to Newton's third law, the force of the sledge on the tractor is equal in magnitude and opposite in direction, also 4900 N. The frictional force exerted on the sledge by the ground is determined to be 2800 N.
