farmhand attaches a 25 Kg bale of hay to one end of a rope passing over a frictionals pulley connected to a beam in the hay barn.then another farmhand pulls down on the opposite end of the rope with force of 277N. ignoring the mass of the rope, find the magntuide and dirction, gravitional force is 245N.

Shhh...
Between you and me...The gravitational force is always directed from the center of the one mass to the center of the other. From the center of bale's mass to the center of the Earth and it should be downward no matter where you are, even if you are in Australia.
(It is 245 Newtons and pointing down)
Now, would you tell me the name of that farmer's daughter.
Okay
Gravitational force
F=W=mg
mg= 25 kg x 9.81m/s^2= 245N
and you thought I was kidding.
