If a string can handle a max tension of 85 N what is the largest mass that could be lifted with this string if it is lifted with an acceleration of 2.0 m/s^2 up on the moon? Let up be positive in value. Ft = - 85 N, a = 2.0 m/s^2, Fg = -1.6 m/s^2 2. Relevant equations F = ma -> Fg = mg -> Ft = ma + mg -> Ft = m ( a + g) 3. The attempt at a solution When I do the problem, I get a negative mass ... Ft = m (a + g) -> -85 N = m ( 2 m/s^2 - 1.6 m/s^2 ) -> m = - 212.5 kg Do you see the mistake?
