A small object is sliding on a smooth horizontal floor along a vertical wall. The wall makes a smooth turn by an angle `theta_(0)` . Coefficient of friction between the wall and the block is `mu`. Speed of the object before the turn is u. Find its speed (V) just after completing the turn. Does your answer depend on shape of the curve? [The turn is smooth and there are no sharp corners.]
