Homework Statement
A hockey puck B rests on a smooth surface of ice and is struck by a second puck A , which was originally traveling at 40.0 m/s and which is deflected 30.0 degrees from its original direction. Puck B acquires a velocity at a 45.0 degree angle to the original direction of A . The pucks have the same mass.
what fraction of the orignal kinetic energy of puck A dissipates during the collision.
Homework Equations
(Delta K) /K
KE=0.5 mv^2
The Attempt at a Solution
i was able to solve for the velocity of both block a and b. But now i can't seem to figure out the original kinetic energy. I do not know where to go with the masses being the same.
Va=29.3 m/s
Vb=20.7
