The pulley is a uniform disk with a mass of 0.75 kg and a radius of 6.5 on between the 5.8 kg mass and the horizontal surface is 0.25, and the
The system is released from rest. Use work-energy principles to deter
2.8 kg mass and (b) the pulley after the 5.8 kg mass has moved 2.2 m

Why does the input force have to be greater than the force needed to lift the bale?

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
