In earlier days, horses pulled barges down canals in the manner shown in Fig. 5-47. Suppose the horse pulls on the rope with a force of 8600 N at an angle of `theta=18^(@)` to the direction of motion of the barge, which is headed straight along the positive direction of an x axis. The mass of the barge is 9500 kg, and the magnitude of its acceleration is `0.12" m"//"s"^(2)`. What are the (a) magnitude and (b) direction (relative to positive x) of the force on the barge from the water ?

Explanation

(a) `7.5xx10^(3)N,` (b) `200.7^(@)` counterclockwise
