An experimental high-speed hyperloop pod is tested on a straight, level track. In an emergency, it relies on a primary magnetic braking system to come to a complete standstill.
Suggest one reason why the actual emergency braking zone designed for this test track is significantly longer than the theoretical minimum stopping distance calculated from the maximum deceleration of the magnetic brakes.
