Your alpine rescue team is using a slingshot to send an emergency packageto climbers stranded on a cliff ledge 270 m above the ground. The climbers are ahorizontal distance of 390 m from the rescuers and the slingshot is at a fixed angle of70◦with respect to the ground. What is the launch speed needed for the package toget to the climbers?
