A) You are sitting in a sled, at rest on a pond covered with
nice, thick, frictionless ice. Your own mass is 93.9 kg, and the
sled's mass is 23.5 kg. You start at rest, and then you jump off
the sled, after which the empty sled is traveling at a speed of
5.25 m/s. What will be your speed on the ice after jumping
off?
0.52 m/s
1.97 m/s
1.64 m/s
1.31 m/s
B ) Now, your mass is 80.6 kg, and the sled's mass is 22.9
kg. The sled is moving by itself on the ice at 4.35 m/s. You
parachute vertically down onto the sled, and land gently. What is
the sled's velocity with you now on it?
0.96 m/s
0.58 m/s
1.63 m/s
1.30 m/s
