Two hockey pucks of equal mass undergo a collision
on a hockey rink. One puck is initially at rest, while
the other is moving with a speed of 5.4 m/s. After the
collision, the velocities of the pucks make angles of
33° and 46° relative to the original velocity of the
moving puck. Determine the speed of each puck after the
The Attempt at a Solution
k so i understand we have two unknowns and thus we should have two unknown equations.
masses equal so they can be cancelled
and we know V2=0 so that whole part is removed
^^ first unknown equation
now when i place it into 1/2mv1i^2+1/2mv2i^2=1/2mv1'^2+1/2mv2'^2
it does not give me the right answer or better yet i do not know how to continue on from this i always get
can someone please explain ...thank you in advance.
