Columbia University Animation Cases Questions




What’s happening here and why is it so diffcult for the astronaut to unstuck himself How is he breaking/bending the conservation of momentum principle? If you were the astronaut. what else would you try to unstuck yourself sooner?


How is it that this person manages to increase in height, breaking/bending the conservation of energy where is the energy coming from

Hint: Last time I checked. shoes have friction


Compared to the”straight”way up. the energy required to circle up the pit is the same, but the distance required is

Hint: Force times distance has the units of energy. The pit also seems pretty steep
