A projectile of mass m 1 moving with a speed v1 in the +x direction strikes a stationary target of mass m2 = 2m1 head-on in an elastic collision. Find the final velocity of the projectile m1.
Hint: You can use the energy and momentum principles.
1. -1/3 v1
2. -1/4 v1
3. -1/5 v1
4. 1/3 v1
5. -1/2 v1
7. -5 v1
8. 3 v1
