A farmer is trying to bring down a couple of bags of cattle feed (mass 70kg) from the 2nd floor (height 2.5m) to the bottom. To do this, he will use a disc pulley to lower the bags down. On one end, a counterweight (mass 55kg) is utilized. The counterweight will start on the ground with the rope attached. When the cattle feed bags are pushed off the edge of the 2nd floor, they will fall down, and the counterweight will be raised up. Additional Givens:Radius of the disc pulley: 0.75m Mass of the disc pulley: 4kg Acceleration of gravity: 10 m/s^2 Question: How fast will the bags of cattle feed be falling the instant before they hit the ground?
