Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Consider a spherical asteroid with a density ρ = 3 g/cm3 and a radiusR = 100 km. If its surface is covered with a thin layer of (loosely bound) regolith, what isthe shortest rotation period it can have without losing the regolith at its equator?
12-16. Estimate the maximum rotation rate of a strengthless asteroid (held together by gravity alone) by setting the rotation speed at the equator equal to the escape velocity. (a) Approximate the asteroid by a spherical body. (Hint: Your answer should depend only on the density of the body, not its size.)

The orbital period of the Earth and Mars are Pg = 365.26 d and P respectively. Assuming circular orbits, the synodic period P, for two planets to be at the same angular position from the Sun can be found using the equation 1 = 686.97 d, %3D Pe Pe a) The last opposition of Mars occurred on 13 Oct 2020. Using the information above, calculate the interval between two consecutive Martian oppositions, and estimate the date of its next opposition. b) It is said that Mars at oppositions near its perihelion occur roughly once every 15 years, with the last event occurring on 27 Jul 2018. Using the synodie period derived, find a more accurate interval, and estimate the date for the next time this event occurs. c) The actual dates for the next Martian opposition and opposition at perihelion are 8 Dec 2022 and 15 Sep 2035, respectively.
