Explanation / Answer

In a tractor pullingcontest, a 2300 kg tractor pulls a 4900 kg sledge with anacceleration of 0.61 m/s^2. If the tractor exerts a horizontalforce of 7700 N on the ground, determine the magnitudes of a.) the force of the tractor on the sledge
F=ma =4900*0.61=2989N

b.) the force of the sledge on the tractor
2989N
c.) the frictional force exerted on the sledge by theground
7700-(2989+2300*0.61)=3308N


a.) the force of the tractor on the sledge
F=ma =4900*0.61=2989N

b.) the force of the sledge on the tractor
2989N
c.) the frictional force exerted on the sledge by theground
7700-(2989+2300*0.61)=3308N
