Teams A and B compete in trackdrive. The lap length is 420.69m and their corrected used energy is equivalent to the caloric content of 400 TRIPLE WHOPPERs® and 900 Big Macs® without cheese, respectively. Their lap times times are (from first to last) 171.32, 153.42, 123.96, 120.1, 112.9, 102.4, 95.89, 93.65, 97.54, 96.32 for A and 133.56, 125.25, 112.78, 107.53, 103.91, 97.23, 95.83, 90.28, 96.62, 99.69 for B (in seconds). What is their point difference in Trackdrive & Efficiency? Give the number in absolute value, rounded to 2 decimals. The Tmin overall is 989.21s with a corrected energy usage of 0.885 times of team A’s. Assume the nutrition information was obtained from the official company datasheets.

Transmission system which consists of pulleys and shafts as shown in the picture. Calculate the revolutions of the shaft 4 in rps in the 2nd decimal.

Elon Musk takes his dirty old pickup truck for a ride in town after a crazy mountain trip. He makes sure that there is enough energy left in his battery pack and then he heads to the car wash and there he checks the tire pressure. The indicator shows 320 kPa. Is it good enough, he wonders as he wants no more laughters about his track after his broken car windows. He decides to ask his favorite FSAE team, Aristurtle, to assist him real quick. What's the value of the rolling resistance Fr of his 3 tones cybertruck when he styles in town at 25m/s. Give your answer in N, in the first decimal.
