- (a) What is the escape speed on a spherical asteroid whose radius is 803 km and whose gravitational acceleration at the surface is 1.75 m/s2? (b) How far from the surface will a particle go if it leaves the asteroid's surface with a radial speed of 1330 m/s? (c) With what speed will an object hit the asteroid if it is dropped from 1811 km above the surface?Consider a planet that has two layers. There is a core, which has density 9.9 x 103 kg/m3 and radius 3.9 x 106 m, and then there is a crust, which has density 4.9 x 103 kg/m3 and sits on top of the core. The planet has a total radius of 16.9 x 106 m. Calculate the acceleration due to gravity at the surface of this planet, in N/kg. Use G = 6.7 x 10-11 N m2/ kg2.
