At equator, Earths radius is about 6370 km. A plane flies in low altitude at constant speed of v=226 m/s. Plane can produce average deceleration of a=18,/s^2 when landing.
How long in seconds would it take the plane to circle Earth at the equator.
You are designing the section of a roller coaster ride shown in the figure. Previous sections of the ride give the train a speed of 12.5 m/s at the top of the incline, which is 38.3 m above the ground. What is the minimum radius you can use for the..
