Two brothers, Frank and Dion, are on roller skates and standing still when they push off from one another. Frank's mass is 103.4 kg. Dion's mass is 51.6 kg. After they push off, Frank has a velocity of -7 m/s. What will Dion's velocity be?
Around -3.5 ( might not be completely right ) Frank has a greater mass to he has a low velocity at first, Dion is around half of his weight so he doesn’t have to use as much force to get more than Frank
