Students perform an experiment to collect data that that can be used to determine the density of an unknown liquid. they have a tall cylinder containing the liquid and some cubes of different sizes but the same known mass mthat all sink in the liquid. they only have a meterstick and a stopwatch to take measurements (a) describe a procedure the students could use to collect the data needed to create a graph that can be used to determine the density of the budincluding the measurements to be taken and any steps to reduce experimental uncertainty

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ํ
=0.381meters and mass ํ=3.1ํํ. initially ํ"is on the ground and ํ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ํ#just before it strikes the ground. assume the pulley bearing is frictionless.
