A boy sleds down a hill and onto a frictionless ice - covered lake at 14.9 m/s. In the middle of the lake is a 1,000 kg boulder. When the sled crashes into the boulder, he is propelled over the boulder and continues sliding over the ice at 14.9 m/s. If the boy's mass is 40.0 kg and the sled's mass is 13.0 kg, what are the speeds (in m/s) of the sled and the boulder after the elastic collision?
