Question:
1. You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is kg and the mass of the sled when empty is kg From shore, someone throws a baseball of mass kg to you, and you catch it; the horizontal component of the ball s velocity is ms What will be the sled s and your speed with respect to the surface of the pond after you catch the ball?
2. This time, your mass is kg and the sled s mass is kg You re on the sled, initially moving to the west at cms From the southern shore, your friend throws a baseball of mass kg which you catch as it s traveling northward with a horizontal velocity component of ms What will be the sled s and your speed after catching the ball?
3. Your mass is 77.0 kg, and the sled s mass is 13.9 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 5.56 m/s. What will be your speed on the ice after jumping off?
