A particle with speed V1= 75 m/s makes a glancing elastic collision with another particle that initially is at rest. Both particles have the same mass. After the collision, the struck particles moves off at an angle that is 45 degrees above the line along V1. The second particle moves off at 45 degree below this line. The speed of the struck particle after the colllision is approximately.
A: 38 m/s
B: 82 m/s
C: 64 m/s
D: 47 m/s
E: 53 m/s
