A 30.0 kg object that is initially at rest explodes and 15 equal masses spread out in different directions, each with a speed of 10.0 m/s. What can be said about the momentum of the system after the explosion? Neglect friction and air resistance. Total momentum is 300.0 kgm/s. Total momentum is 150.0 kgm/s. Total momentum is zero. Total momentum is 20.0 kgm/s. Total momentum can not be determined with the available information.
