The coefficient of friction between box and block are `mu_(s)` and `mu_(k)` . The sliding block encounters an ideal spring with force constant k . Answer the following questions :

Assuming no relative motion between box and block what is the maximum possible acceleration of block and box at the instant of maximum compression ?

A

`mu_(s) g`

B

`(mu_(s) "Mg")/(m)`

C

` (mu_(s) (M + m) g)/(m)`

D

`(mu_(s) "mg")/(M)`

A block of mass M slides on a frictionless surface with an initial speed of v_(0) On top of block is a small box of mass m. the coefficients of friction between box and block are mu_(6) and mu_(k) . The sliding block encounters and ideal spring with force constant K. Answer following questions. Suppose the value of k is just slightly greater then the value found in previous question, so that the box begins to slide just as the spring reaches maximum compression. The acceleration of box and block are repectively.
