A net force causes an object to increase its momentum from 100kgm / s to 300kam / s A. It is probable that there was an increase in mass causing the change in momentum. B. The force causing the change in momentum must have been in the same direction as the initial velocity C.The velocity must have increased by 3m / s order for this momentum change to occur D. The impulse causing the increase in momentum could be equal to 300 N s
