during a hockey game. Alice and Bob are set to collide head-on in the middle of the rink. Alice is twice as massive as bob. fearing for safety, Bob reasons that he should skate twice as fast as Alice to match her momentum to" even the chances", i s bob's reasoning sound, or will he make the situation worse
Mb = Mass of Bob
2Mb = Mass of alice
Va = Velocity of Alice
2Va = Velocity of Bob
Momentum of Alice = (2Mb)Va
Momentum of Bob = Mb(2Va)
as the speed increses by bob make the situation worse .
