COMPREHEN A massless elastic cord that obeys Hooke s law will break if the tension in the cord exceeds Tmax One end of the cord is attached to a fixed point the other is attached to an object of mass 3m as shown in the figure If a second smaller object of mass m moving at an initial speed vo strikes the larger mass and the two stick together the cord will stretch and break but the final kinetic energy of the two masses will be zero If instead the two collide with a perfectly elastic one dimensional collision the cord will still break and the larger mass will move off with a final speed of v All motion occurs on a horizontal frictionless surface assume that Hooke s law is obeyed throughout until the cord breaks Find Y H
