1.	A block of mass M slides on a frictionless surface with an initial speed of v_(0) . On top of block is small box of mass m . The coefficient of friction between box and block are mu_(s) and mu_(k) . The sliding block encounters an ideal spring with forceconstant k . Answer the following questions : Suppose the value of k is just slightly greater than the value found in Q.2 , so that the box beginsto slide just as the spring reaches maximum compression . The accelerations of box and block are respectively :
Answer» `a_("BOX") = mu_(K) G , a_("Block")= (m(mu_(s) - mu_(k)) + mu_(s) M)/(M) g ` `a_("Box") = (mu_(s) - mu_(k)) g , a_("Block") = (mu_(s) - mu_(k)) ( mg)/(M)` `a_("Box") = mu_(k) g , a_("Block") = (mu_(s) + mu_(k)) (mg)/(M)` none of the above ANSWER :A
