Homework Statement
A HOCKEYPLAYER SKATES AT 7.85 M/S AND HAS A MASS OF 120 KG WHEN HE COLLIDES WITH ANOTHER STAIONARY HOCKEY PLAYER. THE SECOND HOCKEY PLAYER IS NOW MOVING AT 5.67 M/S. FIND THE MASS OF THE SECOND HOCKEY PLAYER AND THE SPEED OF THE FIRST. ASSUME THIS COLLISION IS ELASTIC.
Homework Equations
[Rho]playerone + [Rho]player2 == [Rho]playeroneafter + [Rho]player2after
^^^ COnservation of Momentum
And then Another Equation Which Escapes me.
The Attempt at a Solution
Find: Pplayer1, Pplayer2,
How do I find the Mass and Speed?
I have been doing Collision Problems for some time now, but must have gotten hit too hard in hockey, because I am lost!
Many Thanks from Frigid CT
