Two particles, of masses M and 2M, moving, as shown, with speeds of 10 m/s and 5 m/s, collide elastically at the origin. After the collision, they move along the indicated directions with speeds v1 and v2, respectively. The values of v1 and v2 are nearly:

• A. 6.5 m/s and 6.3 m/s
• B. 3.2 m/s and 6.3 m/s
• C. 6.5 m/s and 3.2 m/s
• D. 3.2 m/s and 12.6 m/s
