11 (a) State and prove Kepler's First Law. 8 (b) A smooth sphere impinges on another one at rest. After the collision their directions of motion are at right angle. Show that, if they are elastic, their masses must be equal. Where 2a the major axis, e the eccentricity, and T is the periodic time. 8 11 (a) State and prove Kepler's First Law. 8 (b) A smooth sphere impinges on another one at rest.
