7 A 20.0-kg sled with 70.0-kg driver is sliding down a frictionless slide directed 30.0° below the horizontal at 8.00 m/s when a 55.0-kg woman drops from a tree limb straight down behind the driver. If she drops through a vertical displacement of 2.00 m, what is the subsequent velocity of the sled immediately after impact? (Report answer in 3 SF; unit: m/s) * O
