The drawing shows a boat being pulled by two locomotives through a canal of length 2.50 km. The tension in each cable is 5.00 103 N, and è = 19.0°. What is the net work done on the boat by the two locomotives?

  • physics -

    work= force * distance cosine Theta
    = 2*5000*2500*cos19/2

    I assume the angle between the ropes is 19deg.
