Aspherical asteroid of average density would have a mass of 8.7×1013kg if its radius were 2.0 km. 1. if you and your spacesuit had a mass of 110 kg, how much would you weigh when standing on the surface of this asteroid? express your answer to two significant figures and include appropriate units. 2. if you could walk on the surface of this asteroid, what minimum speed would you need to launch yourself into an orbit just above the surface of the asteroid? express your answer to two significant figures and include appropriate units.
