The asteroid Toro has a radius of about 5.0 km. Consult Appendix F as necessary.

(a) Assuming that the density of Toro is the same as that of the earth (5.5 g/cm³), find its total mass and find the acceleration due to gravity at its surface.

(b) Suppose an object is to be placed in a circular orbit around Toro, with a radius just slightly larger than the asteroid€™s radius. What is the speed of the object? Could you launch yourself into orbit around Toro by running?
