A hand pushes a 3 kg block along a table from point A to point C as shown in the figure below. The table has been prepared so that the left half of the table (from A to B) is frictionless. The right half (from B to C) has a non-zero coefficient of friction equal to µ. The hand pushes the block the full distance from A to C using a constant force of 5 N. The block starts off at rest at point A and comes to a stop when it reaches point C. The distance from A to B is 0.5 m and the distance from B to C is also 0.5 m. We will consider the block by itself as our system so all forces on the block are external. Initial position of block Final position ofblock P no friction friction A B C -1½ m 1½ m
