Questions
A block A of mass M moving with speed u collides elastically with block B of mass m which is connected to block C of mass m with a spring.
When the compression in spring is maximum, the velocity of block C with respect to block A is
(Neglect the friction everywhere)
detailed solution
Correct option is C
Here, vA=M-mM+mu and vB=2MuM+mVelocity of C at maximum compression, vc = vB/2∴ vC=122MM+mu=MM+mu∴ vCA=vC-vA=mM+muTalk to our academic expert!
