Transcribed Image Text:202122: applications, Rolle's theorem, grad. EVE Online is a space-based multi-
player game, where players use spaceships to engage in combat, industry, exploration
and other activities.
a) A player is seeking to travel from her current position in a combat arena to the
exit gate. The gate is located inside a cloud of gas, which is bounded by a plane:
inside this gas, the ship's speed increases from v₁ to v₂. The diagram below
explains the situation: she will travel from point A to point C by way of point
B. (You may assume that any changes in speed or direction are instantaneous.)

ii. The player wishes to choose point B on the boundary in order to minimise
the total travel time from point A to point C. Use calculus to show that,
for this quickest trajectory, the angle 02 depends on 0₁ according to the
