Two identical blocks A and B , each of mass m resting on smooth floor, are connected by a light spring of natural length L and the spring constant k , with the spring at its natural length. A third identical block C (mass m ) moving with a speed (v) along the line joining A and B collides with A . The maximum compression in the spring is proportional to
Options
- Av m 2 k
- Bm v 2 k
- Cm v k
- Dm v 2 k
Correct answer
A. v m 2 k
Step-by-step solution
When block (C) strikes the block (A) , then it begins to oscillate, whose time period T=2 m 2 k Compression, x=v T=v 2 2 k x v m 2 k
