An astroid of mass 2.1 x 10^15 kg splits apart. Asume the original astroid was at rest.
a) what was the intioal momentum of the system?
b) If the astroid breaks into a first piece moving (-31 m/s) x and the second has a mass of 1.8 x 10^15, in which direction do you expect the second peice to move. Explain
c) what is the final velocity of the larger piece after the break?
