a hockey player skates across the pond with constant velocity V and hits a park Straight Ahead toward the goal we can assume there is no friction after the plug is hit what is the velocity of the center of the mass of the hockey player Puck system​

Not sure but i think it's b.

We can not use the law of conservation of energy here. we will use the law of conservation of momenta. we will break into two components, the x component will represent east, and y component will represent north.solving this system will give us the velocity of the third mass.we can plug this backi into the first equation: with this angle we can now calculate the velocity:
