A puck of mass m1 is moving along a frictionless table at speed v1 in the +x-direction when it is hit simultaneously by 2 lumps of clay, each of mass m2. Both lumps are traveling at speed a speed of v2. One is traveling in the -x-direction, while the other one is dropped from above the table in the -y-direction. The puck and lumps of clay stick together. What is the speed of the puck and clay after the collision?

A. sqrt((m1v1-m2v2)2+(m2v2)2) / m1+2m2

B. m1v1 / m1+2m2

C. sqrt((m1v1-m2v2)2+2*(m2v2)2) / m1+2m2

D. m1v1-2m2v2 / m1+2m2

E. m1v1-m2v2 / m1+2m2
