    What Speed Does the Man Hit the Ground?

    both accelerations should be the same shouldn't it? so this is what i have so far... Sum of forces for m1: Ft - m1g Sum of forces for m2: m2g - Ft m1a = Ft - m1g m2a = m2g - Ft Ft = m2g - m2a m1a = ( m2g - m2a ) - m1g m1a + m2a = m2g - m1g 80a + 60a = 60*9.8 - 80*9.8...
