You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 63.2 kg, and the mass of the sled when empty is 10.6 kg. From shore, someone throws a baseball of mass 0.145 kg to you, and you catch it; the horizontal component of the ball s velocity is 34.8 m/s. What will be the sled s (and your) speed with respect to the surface of the pond after you catch the ball? 47.0 cm/s 3.41 cm/s 6.82 cm/s 7.97 cm/s 0000

This time, your mass is 62.6 kg and the sled s mass is 23.3 kg. You re on the sled, initially moving to the west at 6.94 cm/s. From the southern shore, your friend throws a baseball of mass 0.159 kg, which you catch as it s traveling northward with a horizontal velocity component of 24.3 m/s. What will be the sled s (and your) speed after catching the ball? 6.16 cm/s O 16.5 cm/s 5.78 cm/s 8.25 cm/s
