In the wood machine shown below, m₁= 2.00 kg and m₂= 7.70 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 v -initial= 2.60 m/s downward.
