🤓 Based on our data, we think this question is relevant for Professor Koslover's class at UCSD.

A particle with mass m moving at speed v collides with a particle with mass 2m initially at rest. After the collision, the two particles have velocities that are directed at equal angles of θ on either side of the original line of motion of the m particle. What is the speed v' of the 2m particle after the collision?

1. v' = v/4sinθ

2. v' = v/cosθ

3. v' = vsinθ/4

4. v' = v/4cosθ

5. v' = vcosθ

6. v' = v/2cosθ

7. v' = vsinθ/2

8. v' = v/sinθ

9. v' = vcosθ4
