A spherical asteroid with a radius of 11 km approaches Earth with a speed 0.3c. What is the volume of the asteroid as determined by an Earth-based observatory. (The volume of an ellipsoid with semi-axis a,b, and d is 4π*a*b*d/3).
Consider a spherical asteroid with a radius of 20 km and a mass of 9.25 ✕ 1015 kg. Assume the asteroid is roughly spherical. (a) What is the acceleration due to gravity on the surface of this asteroid? m/s2 (b) Suppose the asteroid spins about an axis through its center, like the Earth, with a rotational period T. What is the smallest value T can have before loose rocks on the asteroid's equator begin to fly off the surface? h

*The escape speed from the surface of the Earth is 11.2 km/s. Estimate the escape speed for a spacecraft from the surface of the Moon. The Moon has a mass 1/81 that of Earth and a radius 0.25 that of Earth. (2 pts) A) 2.5 km/s B) 4.0 km/s C) 5.6 km/s D) 8.7 km/
1. Ceres is the largest asteroid. Its mean radius is 476 km and its mass is 9.4×10^20 kg. Using this, and G=6.67×10^−11 Nm^ 2 kg^−2, and approximating it as a sphere, compute the speed required to escape the gravity on the surface of Ceres. Speed= ___ m.s^−1. (to two significant figures, don't use scientific notation) 2. Consider the mechanical energy of a body in geostationary orbit above the Earth's equator, at rGS = 42000 km. Consider the mechanical energy of the...
3questions in total please *Problem 6.66 You stand on a spherical asteroid of uniform density whose mass is 2.5 x 1016 kg and whose radius is 11 km (11 x 103 m). These are typical values for small asteroids, although some asteroids have been found to have much lower average density and are thought to be loose agglomerations of shattered rocks. You want to figure out how fast you have to throw the rock so that it never comes back...
