A particle of mass 7.22 x 10^-27 kg, moving at 7.06 x 10^5 m/s, strike an identical particle which is initially at rest. After the interaction, the particles, are observed moving at angles of 53 and 37 degrees, both angles being measured with respect to the original direction of motion. What are the final speeds of the particles?
At 53 degrees?
At 37 degrees?
