Q.6. A wagon of mass 200 kg is tied to a horse by a rope. The horse pulls the wagon at a constant speed of 3 m s-1, with a force of 40 N in the horizontal rope.
(a) Explain why the horse needs to exert a force in order to pull the wagon at a constant speed.
(b) With the aid of calculations, explain how the force in the rope changes if the horse accelerates at 0.1 m s-2.

Solution

Dear student,a) The horse need to exert a force so as to change the state of rest of the waAs according to Newton's law of motion only force can bring a change in the statae of motion of a body.b) initial acceleration of the wagon=40200=0.2m/s2Now the new accelaeation =0.1m/s2Force in the rope=200×0.1=20NRegards
