2. A 64 kg woman flies in a plane, 5,334 m above sea level. What is her gravitational potential energy?

The answer would be d. hope this : ))

All u need to do is see how 50cm work with each other

We can not use the law of conservation of energy here. we will use the law of conservation of momenta. we will break into two components, the x component will represent east, and y component will represent north.solving this system will give us the velocity of the third mass.we can plug this backi into the first equation: with this angle we can now calculate the velocity:
