Your self-developed electronic control module needs 200ms to safely shut down and write back data into nonvolatile memory.
How big would the power regulator output capacitance need to be at least to do that in the event of a unexpected shutdown (GLV Master switch turn-off), given that:

+ The device needs a constant current of 120mA
+ The regulated voltage is 5V
+ The CPU will brown-out at 3.8V
+ There is no reverse-flow back into the supply

An off-course can be avoided if the driver re-enters the track at or before the point he left it
The time penalty for an off-course is 10s
An off-course during the skidpad event leads to a DNF for that run
An off-course occurs if a vehicle is outside the track boundary with all four wheels

During charging you monitor the cell temperatures by tapping the BMS CAN Bus. The Temperature is transmitted as 16-bit unsigned integer (0.00229 °C/bit).
Looking at the data the temperatures look somewhat implausible (see picture below) - what went wrong most likely?

The endianess is wrong
The conversion factor is wrong
The can bus is overloaded
The signed-ness is wrong
This is actually the cell voltage

Which of the following statements about the legality of the car below is true?

+ track width = 2500mm
+ car track = 1700mm
+ cone height = 280mm
+ rear wing height = 2100mm
+ roll hoop height = 2200mm

rear wing is too wide
front wing overall width is too wide
the structure around the cone slots is too high
cone slots would have to be movable (illegal movable aero devices)
endplate gurneys are generally not allowed
