As shown a block (Object -A) of mass `m_(A)` moves on a frictionless plane at initial speed `v_(0)`, and land onto a cart (Object-B in the figure, mass `m_(B)`, length `L` initially at rest) smoothly. Ignore the size of the block. The firction coefficient between A and B is `mu` and the cart is no a frictionless plane. The block collides elastically on the fixed wall at the end of the cart and eventually falls off the cart.

Suppose the initial speed is larger than the minimum value in above question
