Famer attaches 25kg bale of hay to one end of rope passing over a frictionless pulley connected to beam in hay barn. Another farmer pulls down on opposite end of rope with force of 277 N. Ignoring mass of rope, what will be the magnitude and direction of the bale's acceleration if the gravatational force acting on it is 245 N?

f=ma
1.3 m/s^2 upward
i think i had this exact question on a test 3 of weeks ago

Net force on the bale = 277 - 245 = 32N
f = ma
a = f/m = 32/25 = 1.28m/s^2 upward

in case you're preserving it above your head and its no longer shifting, there is not any internet rigidity. The rigidity of gravity is hostile by utilizing the conventional contact rigidity of your hand. in case you enable pass, the rigidity will be one newton(the apple's weight).
