Question No 3 A block with mass m is located at position x 0 on a horizontal table A spring with spring constant k and relaxed length zero is connected to it and has its other end anchored at position x f as shown in the fig The coefficient of friction both static and kinetic between the block and the table depends on position according to AX where A is a constant Assume that the block is small enough so that it touches the table at essentially only one value of x O O 3k A mg peeleel Ax If the stopping point is to the right of the anchor the condition on A for which the block start moving leftward after it instantaneously comes to rest is Assume that the block can some how pass through the anchor O k A 3mg 4k A mg m x 0 x
