Mathematics · Collisions and Mechanics
Two spheres S1 and S2 of masses m1 and m2 respectively collide with each other. Initially S1 is at rest and S2 is moving with velocity v along the x-axis. After collision, S2 has a velocity v2 in a direction perpendicular to the original direction. Sphere S1 moves after collision with a velocity of magnitude:
- 1m12m2 v √5
- 2m22m1 v
- 3m1m2 v √52
- 4m2m1 v √52✓
Correct answer
m2m1 v √52
