Aject airliner moving initially at 30 mph due east enters a region where the wind
is blowing at loomph in a direction 30 degree north
of east what is the new velocity of the aircraft
relative to the ground?​

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

ill do it for 100, also this isnt 80 its 40

inverse v=i*r

nice nice
