Unformatted text preview: Solution: Again, we start with a free-body diagram. Now, again the forces are all along the FT y x Fg same (y) axis. So Newton's law reads FT + Fg = may . Now, in this problem, ay is not zero, it is in fact 0.80 m/s2 . So, putting the quantities we know into the euqaiton above, we get FT + 1200 kg (-9.8 m/x2 ) = 1200 kg 0.80 m/s2 , which is easily solved to find FT = 12720 N. ...
