You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 71.7 kg, and the mass of the sled when empty is 21.1 kg. From shore, someone throws a baseball of mass 0.141 kg to you, and you catch it; the horizontal component of the ball s velocity is 30.1 m/s. What will be the sled s (and your) speed with respect to the surface of the pond after you catch the ball?
