Two men, on either bank of a canal, pull a boat that moves at a constant speed on a straight path in the middle. The men pull through ropes withF₁ =F₂ = 300 N forces that make a 30 angle with the path of the boat.

A. Set up the problem with a labeled diagram.

b. Calculate the total force F that pulls the boat and the resistance R of the water on the boat.

c. Calculate the work W after the boat has moved 80 m along the canal.
