Two groups of canoeists meet in the middle of a lake. After a brief visit, a person in canoe 1 pushes on canoe 2 to separate the canoes. Suppose the speeds of the two canoes after they are pushed apart are 0.52 m/s for canoe 1 and 0.38 m/s for canoe 2. If the mass of canoe 1 is 300 kg , what is the mass of canoe 2?

    Two groups of canoeists meet in the middle of a lake. After a brief visit, a person in canoe 1 pushes on canoe 2 to separate the canoes. Suppose the speeds of the two canoes after they are pushed apart are 0.60 m/s for canoe 1 and 0.46 m/s for canoe 2. If the mass of canoe 1 is 310 kg , what is the mass of canoe 2? ____kg

    A boy sleds down a hill and onto a frictionless ice-covered lake at 14.4 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 14.4 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? (Due to...

    Three ice skaters meet at the center of a rink and each stands at rest facing the center, within arm's reach of the other two. On a signal, each skater pushes himself away from the other two across the frictionless ice. After the push, skater A with mass mA = 75.0 kg moves in the negative y-direction at 4.00 m/s and skater B with mass mB = 80.0 kg moves in the negative x-direction at 3.50 m/s. Find the x-...
