Reference no: EM13537415

In mid-nineteenth century England horses were often used to pull barges along canals. The horse, naturally, trudged along a path parallel to the canal and so the rope to the barge was at an angle to the motion of the barge.

a) If such a horse was pulling with a force of 155 N at a speed of 12.60 km/h and the angle of the rope with respect to the canal direction was 35.0 degrees how much work (in KJ) does the horse do in 9.1 minutes ?

b) What is the average power ? (Give your answer in HP, Remember: 1HP = 746 W)
