(a) What is the escape speed on a sphericalasteroid whose radius is 570 km and whose gravitationalacceleration at the surface is 3.3 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
Determine the maximum percent uncertainty it will produce in this experiment if we did not align the apparatus to minimize its effects
