Abead of mass m under the influence of gravity slides along a frictionless and massless wire whose height is given by a function y(x). assume that at position (x, y) = (0, 0) the tangent of the wire is horizontal and the bead passes this point with a given speed v0. what should y(x) be so that the horizontal speed remains v0 at all times (that is what is the shape of the wire)? one simple solution is y = 0, find the other solution. (hint: it should

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