The package handing system is designed to launch the small package of mass $m$ from $A$ by using a compressed linear spring of constant $k.$ After launch, the package slides along the track until it lands on the conveyor belt at $B.$ The track has small, well$-$oiled rollers so that you can negle$$ct any energy loss due to the movement of the package along the track. Modeling the package as a particle, determine the minimum initial compression of the spring so that the package gets to $B$ without separating from the track at $C.$ Finally, determine the speed with which the package reaches the conveyor at $B.$
