because they have enough water
Explanation:
Centre of Mass then axis of rotation and then moment of inertia. This was the toughest question for your level... happy to help ^_^. It was purely experimental question.
Answer:
0.4 m/s
Explanation:
Law of conservation of momentum tell us that the change in momentum of the hammer will be equal to the change in momentum of the astronaut
change in momentum of hammer = change in momentum of astronaut
2 kg (14 m/s - 0 m/s) = 70 kg * (v-0)
v = 0.4 m/s
Answer:
993 m or 3257 ft
Explanation:
The captain was told to fly at at 1500 ft altitude. At the rate of 3.28 ft to 1 m, this is
metres.
Since he was at 1450 m, he thought he was above the correct altitude by
1450 - 457 = 993 m.
In feet, this is
993 * 3.28 = 3257 ft
