They have to bring down a couple bags of cattle feed from the 2nd floor of their barn, to the bottom. To do this they will use a disc pulley to lower the two bags of cattle feed down. As a counter weight, they will use their friend Stewart. Stewart will start on the ground with the rope attached to him, and since Stewart has a lower mass than the two bags of cattle feed, when they put the cattle feed over the edge on the 2nd floor, the cattle feed will fall down, and Stewart will be raised up. Using the givens below, calculate how fast the bags of cattle feed will be falling the instant before they hit the ground. Mass of Stewart: 55 Kg Mass of the two bags of cattle feed: 70 Kg Height of the 2nd floor of the barn: 2.5m Radius of the disc pulley: 0.75m Mass of the disc pulley: 4 kg Acceleration of Gravity: 10arrow_forwardThe figure below shows a bird feeder that weighs 199.9 N.
