1) During Acceleration event in FSG, a car is travelling with a speed of 99km/h when a bolt holding the right side of the front wing suddenly brakes. A part of it is launched parallel to the ground with velocity of 126km/h and hits the center of the finish line cone. Calculate the distance of the car from the finish line. Round the solution to 2 decimals.
Given:
Cone’s height: 505mm
Height of the bolt from the ground: h = 40cm
Chassis cross section: 350mm
g = 9.81 m/s2

9. In physics, geosynchronous orbit is called the orbit for which a satellite stays over the exact same place on earth. Given that:
- Constant of gravity G = 6.67 × 10-11 N×m2/kg2
- Earth’s mass: ME = 5.97 × 1024 kg
- Earth’s radius: R = 6.37 × 106 m
