What speed is needed to escape from the surface of a spherical, homogeneous asteroid with a radius of 5.00 km and a density of 3200 kg/m3? The asteroid has no atmosphere.

A certain spherical asteroid has a mass of 3.5 * 10^16 kg and aradius of 8.8 km. What is the minimum speed needed to escape fromthe surface of this asteroid?
(G = 6.67 * 10^-11 (N*m^2)/kg^2)

Escape Speed
(a) What is the escape speed on a spherical asteroid whose radiusis 570 km and whose gravitational acceleration at the surface is10.0 m/s2?
m/s
(b) How far from the surface will a particle go if it leaves theasteroid's surface with a radial speed of 1000 m/s?
m
(c) With what speed will an object hit the asteroid if it isdropped from 1000 km above the surface?
m/s
