In the atwood machine shown below, m1 = 2.00 kg and m2 = 6.05 kg. the masses of the pulley and string are negligible by comparison. the pulley turns without friction and the string does not stretch. the lighter object is released with a sharp push that sets it into motion at vi = 3.00 m/s downward.. (a) how far will m1 descend below its initial level?
