A barge is being pulled through a canal by two horses, as shown in
Figure 2.27a. If each horse applies a force of 5000 N, determine the frictional
force applied by the water as the barge moves to the right at a constant speed.
the answer should be 7.7 x 103 N [left].
but I don't know how to find it all I got was Fx1=3831 N for one horse and the same for the other. I also got Fy for both horses which is 3214 N
the equation that I used to find Ff is Fx1+Fx2-Ff=ma
i don't know how to go on from there!
